Detailed Description

An observable class for the electroweak Peskin-Takeuchi pseudo-observables.

Author
HEPfit Collaboration

This class is used to compute the observables S, T and U. Formulae from equations (21), (22) and (23) in [21].

double STU::F ( const double  m02,

[in]m12mass square \(m_1^2\)
Returns
the function F for THDM
