Detailed Description

A class for \(R(\Delta M_{B_d})\), the ratio of the total difference in mass of between the heavy and light mass eigenstates of the neutral \(B_d\) system, over the SM difference.

This class is used to compute the theoretical value of \(R(\Delta M_{B_d})\). The short distance contributions to this parameter is calculable both in the SM and in NP models. In the SM the short distance contribution is dominated by the top loop in the box diagram.
