Abstract
The entropy production scenarios due to the electroweak phase transition (EWPT) in the framework of the minimal extension of standard model, namely the two Higgs doublet model (2HDM), are revisited. The possibility of first order phase transition is discussed. Intense parameter scanning was done with the help of BSMPT, a C++ package. We perform numerical calculations in order to calculate the entropy production with numerous benchmark points.
Highlights
We considered electroweak phase transition (EWPT) in real type-I 2HDM and did not take into account any g-2 anomaly
BSMPT [20,21,22] is a C++ tool used for calculating the strength of the electroweak phase transition in extended Higgs sectors
We demonstrated in this paper that, even in the minimal extension of SM with two
Summary
Adding virtual particles and loop corrections, the calculated value of gμ − 2 /2 in SM was 116,591,810(43) × 10−11, (see Equation (3) and Equation (2) of [2]) while the measured value from FERMILAB was 116,592,061(41) × 10−11 [2,3] The detection of this anomaly has buttressed previous claims about the disaccord between the theoretical and experimental results [4]. G?,s is the effective number of degrees of freedom in entropy, and it is not constant over time. It depends on the components of the primordial hot soup, it is not always the same as g?
