Detailed Description

A model class for new physics in the form of contributions to the \(\varepsilon_{1,2,3,b}\) parameters.

Author
HEPfit Collaboration

This is a Model class containing parameters and functions to work with the epsilon paramterization [10], [11],[12] for new physics contributions to the electroweak precision observables. It is noted that the \(\varepsilon_{1,2,3,b}\) parameters include both the SM and new physics contributions.

Initialization

The constructor NPEpsilons() initializes the model flags explained below to their default values. After creating an instance of the current class, it is required to call the initialization method InitializeModel(). This pointer is then used in computing the \(W\)-boson mass and the fermionic neutral-current couplings with the epsilon parameters. In the Monte Carlo run, the constructor as well as the initialization method are called in InputParser::ReadParameters().

Model parameters

The model parameters of NPEpsilons are summarized below:

Label LaTeX symbol Description
epsilon_1 \(\varepsilon_1\) The parameter \(\varepsilon_1\).
epsilon_2 \(\varepsilon_2\) The parameter \(\varepsilon_2\).
epsilon_3 \(\varepsilon_3\) The parameter \(\varepsilon_3\).
epsilon_b \(\varepsilon_b\) The parameter \(\varepsilon_b\).

Model Flags

The flags of NPEpsilons are summarized below:

Label Value Description
epsilon1SM TRUE / FALSE This flag is set to TRUE if only the SM contribution is considered for \(\varepsilon_1\). The default value is FALSE.
epsilon2SM TRUE / FALSE This flag is set to TRUE if only the SM contribution is considered for \(\varepsilon_2\). The default value is FALSE.
epsilon3SM TRUE / FALSE This flag is set to TRUE if only the SM contribution is considered for \(\varepsilon_3\). The default value is FALSE.
epsilonbSM TRUE / FALSE This flag is set to TRUE if only the SM contribution is considered for \(\varepsilon_b\). The default value is FALSE.

Important member functions

Compared to the base class NPbase, the functions for the following quantities are reimplemented in the current class:

  • \(M_W\)   (with Mw()),
  • \(\Gamma_W\)   (with GammaW()),

where the latter is not available, since it cannot be simply parameterized by the epsilon parameters. In addition, the functions for the epsilon parameters are also provided:

The effective neutral-current coupling \(\kappa_Z^f\).

The \(Zf\bar{f}\) effective coupling \(\kappa_Z^f\) for \(f\neq b,t\) is flavour universal in the original version of the epsilon parameterization:

\[ \kappa_Z^f = \kappa_Z^e(\varepsilon_1,\varepsilon_3). \]

See kappaZ_e() for \(\kappa_Z^e(\varepsilon_1,\varepsilon_3)\). When StandardModel::FlagWithoutNonUniversalVC is true, the flavour non-universal vertex corrections are also taken into account:

\[ \kappa_Z^f = \kappa_Z^e(\varepsilon_1,\varepsilon_3) + \Delta\kappa_Z^f, \]

where \(\Delta\kappa_Z^f\) denotes the non-universal corrections given by StandardModel::kappaZ_f_SM_FlavorDep().

The radiative corrections to \(M_W\) is parameterized in terms of the quantity \(\Delta r\):

\[ M_W^2 = \frac{M_Z^2}{2} \left( 1+\sqrt{1-\frac{4\pi\alpha}{\sqrt{2}G_\mu M_Z^2(1-\Delta r)}}\ \right)\,, \]

where \(\Delta r\) contains both SM and NP contributions, and is resummed. In [10] and [11], \(\Delta r\) is given in terms of \(\Delta r_W\):

\[ \Delta r = 1 - [1 - \Delta\alpha(M_Z^2)][1-\Delta r_W(\varepsilon_1,\varepsilon_2,\varepsilon_3)]\,, \]

where \(\Delta r_W\) is a function of \(\varepsilon_1\), \(\varepsilon_2\) and \(\varepsilon_3\). See Delta_rW().
