#include <StandardModel.h>
Inheritance diagram for StandardModel:A model class for the Standard Model.
This is a Model class containing parameters and functions associated with the Standard Model. This class is inherited from the QCD class, which defines parameters related to QCD.
The constructor StandardModel() initializes some of the model flags to their default values. After creating an instance of the current class, it is required to call the initialization method InitializeModel(), which allocates memory to the pointers defined in the current class. These pointers are then used in computing EW precision and flavour observables, respectively. In the Monte Carlo run, the constructor as well as the initialization method are called in InputParser::ReadParameters().
The initializations and updates of the model parameters and flags are explained below.
The model parameters of StandardModel are summarized below:

The set of the model parameters are initialized and updated with the methods Init() and Update(), respectively, where the former calls the latter actually. In Update(), the methods PreUpdate() and PostUpdate() are called to run all the procedures that are need to be executed before and after the model parameters are updated. The CKM and PMNS matrices and the Yukawa matrices are recomputed in PostUpdate() with the updated parameters. Inside the Update() method, the individual model parameter is assigned with the protected member function setParameter().
The parameters delMw, delSin2th_l, delSin2th_q, delSin2th_b, delGammaZ, delsigma0H, delR0l, delR0c, delR0b represent theoretical uncertainties in the \(W\)-boson mass, the leptonic and quark effective weak mixing angles at the \(Z\)-boson mass scale, the total decay width of the \(Z\) boson, the hadronic cross section at the peak, and the ratios \(R_l^0\), \(R_c^0\) and \(R_b^0\), respectively, originating from missing higher-order corrections. The contributions from these parameters are incorporated into their two-loop approximate formulae: EWSMApproximateFormulae::Mw(), EWSMApproximateFormulae::sin2thetaEff_l(), EWSMApproximateFormulae::sin2thetaEff_q(), EWSMApproximateFormulae::sin2thetaEff_b(), EWSMApproximateFormulae::X_full_2_loop("GammaZ"), EWSMApproximateFormulae::X_full_2_loop("sigmaHadron"), EWSMApproximateFormulae::X_full_2_loop("R0_lepton"), EWSMApproximateFormulae::X_full_2_loop("R0_charm") and EWSMApproximateFormulae::X_full_2_loop("R0_bottom"). Therefore, the parameters are applicable only when the corresponding approximate formulae are employed. See also the model flags below.
The flags of StandardModel are summarized below, where the values of the boolean flags (TRUE or FALSE) are case insensitive, while those of the other flags are case sensitive. The default values of the flags are indicated in bold:
| Label | Value | Description |
|---|---|---|
| Wolfenstein | TRUE / FALSE | This flag controls the way the CKM matrix is parameterized. If set to TRUE, the CKM matrix is computed starting from the Wolfenstein parameters. If set to FALSE, the CKM matrix is computed starting from \(\vert V_{us} \vert\), \(\vert V_{cb} \vert\), \(\vert V_{ub} \vert\) and \(\gamma\). The default value is TRUE. |
| CacheInStandardModel | TRUE / FALSE | This flag controls the use of the cashing method implemented in EWSM class. The default value is TRUE. |
| CacheInEWSMcache | TRUE / FALSE | This flag controls the use of the cashing method implemented in EWSMcache class. The default value is TRUE. |
| WithoutNonUniversalVC | TRUE / FALSE | This flag controls if flavour non-universal vertex corrections are not added to the epsilon parameterization for the EW precision observables. The default value is FALSE; the non-universal corrections are taken into account. |
| NoApproximateGammaZ | TRUE / FALSE | This flag is set to true if the two-loop approximate formulae of the partial and total decay widths of the \(Z\) boson defined with the function EWSMApproximateFormulae::X_full_2_loop() are NOT employed. The default value is FALSE. |
| Mw | NORESUM / OMSI / INTERMEDIATE / OMSII / APPROXIMATEFORMULA | This flag controls the formula used in computing the \(W\)-boson mass. The default flag is APPROXIMATEFORMULA. See EWSM::Mw_SM(), EWSM::resumMw() and EWSMApproximateFormulae::Mw() for detail. |
| RhoZ | NORESUM / OMSI / INTERMEDIATE / OMSII | This flag controls the formula used in computing the \(Zf\bar{f}\) couplings \(\rho_Z^f\). The default flag is NORESUM. See EWSM::rhoZ_l_SM(), EWSM::rhoZ_q_SM() and EWSM::resumRhoZ() for detail. |
| KappaZ | NORESUM / OMSI / INTERMEDIATE / OMSII / APPROXIMATEFORMULA | This flag controls the formula used in computing the \(Zf\bar{f}\) couplings \(\kappa_Z^f\). The default flag is APPROXIMATEFORMULA. See EWSM::kappaZ_l_SM(), EWSM::kappaZ_q_SM() and EWSM::resumKappaZ() for detail. |
| SMAux | TRUE / FALSE | This auxiliary flag is used for testing new options. The default value is FALSE. |
These flags can be set via the method setFlag() or setFlagStr(), where the former is applicable for the boolean flags, while the latter is for the other flags. The method CheckFlags() is responsible for checking whether the flags are sane. The public member functions IsFlagWithoutNonUniversalVC(), IsFlagNoApproximateGammaZ() getFlagMw(), getFlagRhoZ() and getFlagKappaZ() are used to retrieve the values of each flag.
The first two flags CacheInStandardModel and CacheInEWSMcache for the cashing methods in EWSM and EWSMcache classes are relevant to the computations of the electroweak precision observables. Those caches are effective when the \(W\)-boson mass, the decay widths of the \(Z\) boson and the \(Zf\bar{f}\) effective couplings \(\kappa_Z^f\) are calculated without using their two-loop approximate formulae.
The on-mass-shell renormalization scheme [168], [160], [34], [35] is adopted for UV divergences, and the weak mixing angle is defined in terms of the physical masses of the gauge bosons:
\[ s_W^2 \equiv \sin^2\theta_W = 1 - \frac{M_W^2}{M_Z^2}\,, \]
and \(c_W^2=1-s_W^2\).
The Fermi constant \(G_\mu\) in \(\mu\) decay is taken as an input quantity instead of the \(W\)-boson mass, since the latter has not been measured very precisely compared to the former. The relation between \(G_\mu\) and \(M_W\) is written as
\[ G_\mu = \frac{\pi\,\alpha}{\sqrt{2} s_W^2 M_W^2} (1+\Delta r)\,, \]
where \(\Delta r\) represents radiative corrections. From this relation, the \(W\)-boson mass is calculated as
\[ M_W^2 = \frac{M_Z^2}{2} \left( 1+\sqrt{1-\frac{4\pi\alpha}{\sqrt{2}G_\mu M_Z^2}\,(1+\Delta r)}\ \right). \]
The interaction between the \(Z\) boson and the neutral current can be written in terms of the effective \(Zf\bar{f}\) couplings \(g_{V}^f\) and \(g_{A}^f\), of \(g_{R}^f\) and \(g_{L}^f\), or of \(\rho_Z^f\) and \(\kappa_Z^f\):
\begin{eqnarray} \mathcal{L} &=& \frac{e}{2 s_W c_W}\, Z_\mu \sum_f \bar{f} \left( g_{V}^f\gamma_\mu - g_{A}^f \gamma_\mu\gamma_5 \right)\, f\,, \\ &=& \frac{e}{2s_W c_W}\, Z_\mu \sum_f \bar{f} \left[ g_{R}^f \gamma_\mu (1 + \gamma_5) + g_{L}^f \gamma_\mu (1 - \gamma_5) \right]\, f\,, \\ &=& \frac{e}{2 s_W c_W}\sqrt{\rho_Z^f}\, Z_\mu \sum_f \bar{f} \left[( I_3^f - 2Q_f\kappa_Z^f s_W^2)\gamma^\mu - I_3^f\gamma^\mu\gamma_5\right]\,f\,, \end{eqnarray}
where \(\rho_Z^f\) and \(\kappa_Z^f\) are related to \(g_{V}^f\) and \(g_{A}^f\) as the relations:
\begin{eqnarray} g_V^f &=& \sqrt{\rho_Z^f} I_3^f (1 - 4|Q_f|\kappa_Z^fs_W^2) = \sqrt{\rho_Z^f} (I_3^f - 2Q_f\kappa_Z^fs_W^2)\,, \qquad g_A^f &=& \sqrt{\rho_Z^f} I_3^f\,, \end{eqnarray}
and
\begin{eqnarray} \rho_Z^f &=& \left( \frac{g_A^f}{I_3^f} \right)^2, \qquad \kappa_Z^f &=& \frac{1}{4|Q_f|s_W^2} \left( 1 - \frac{g_V^{f}}{g_A^{f}}\right). \end{eqnarray}
The current class handles the following quantities:
Moreover, the functions Mzbar(), MwbarFromMw(), MwFromMwbar() and DeltaRbar_SM() can be used for the quantities in the complex-pole/fixed-width scheme.
The formulae used for the \(W\)-boson mass \(M_W\) and the effective couplings \(\rho_Z^f\) and \(\kappa_Z^f\) are controlled with the model flags Mw, RhoZ and KappaZ of StandardModel. For each flag, the available schemes are as follows:
The scheme APPROXIMATEFORMULA provides the most accurate SM predictions for \(M_W\) and \(\kappa_Z^f\), while the approximate two-loop formula is not available for \(\rho_Z^f\).
See resumMw(), resumRhoZ() and resumKappaZ() for details on the other schemes.
This class contains caching methods for the following functions: DeltaAlphaLepton(), DeltaAlpha(), Mw_SM(), GammaW_SM(), rhoZ_l_SM(), rhoZ_q_SM(), kappaZ_l_SM() and kappaZ_q_SM(), to improve the performance of the Monte Carlo run. The caching methods are implemented with the function checkSMparams().
The use of the caching methods can be controlled with the model flag CacheInStandardModel of StandardModel.

A method to compute the \(W\)-boson mass from \(\Delta\rho\) and \(\Delta r_{\mathrm{rem}}\).
This function computes the \(W\)-boson mass without or with resummation of \(\Delta r\), depending on the model flag Mw of StandardModel:
where the OMS-I, INTERMEDIATE and OMS-II schemes are adopted in ZFITTER [39] (see also [110], [109], [107], [33]), and used for making comparisons to the outputs of ZFITTER. The full two-loop EW contribution is included in the case of "NORESUM", while the large- \(m_t\) expansion for the two-loop contribution is adopted in the other cases.
In the case of "NORESUM", the two-loop EW contribution to \(\Delta r\) is calculated via the function EWSMApproximateFormulae::DeltaR_TwoLoopEW_rem(), given in the complex-pole/fixed-width scheme. The \(W\)-boson mass in the complex-pole/fixed-width scheme, obtained from \(\Delta r\), is converted into the one in the experimental/running-width scheme with the function MwFromMwbar().

The singlet vector corrections to the hadronic \(Z\)-boson width, denoted as \(R_V^h\).
In addition to the final-state corrections represented by the radiator factors \(R_V^q(M_Z^2)\) and \(R_A^q(M_Z^2)\), there exist singlet vector corrections to the total hadronic width [58], [29], which is much smaller than the other corrections.
The assignment of the singlet vector corrections to the partial widths is ambiguous [40]. See Gamma_had() for our prescription.

Top-mass corrections to the \(Zb\bar{b}\) vertex, denoted by \(\tau_b\).
The large top-quark mass gives important corrections to the EW observables through the gauge-boson self-energies, i.e., \(\Delta\rho\), and through the \(Zb\bar{b}\) vertex. The latter contribution is parameterised by the quantity \(\tau_b\):
\[ \tau_{b} = -2\, X_t^{G_\mu} \left[ 1 - \frac{\pi}{3}\alpha_s(M^2_t) + X_t^{G_\mu} \tau^{(2)} \left( \frac{M_t^2}{m_h^2} \right) \right], \]
