The KL-KS mass difference

Author

Summary, in English

The matching of the log and short distance contributions to the KL-KS mass difference is investigated in the large Nc limit (Nc being the number of colours). In this limit a physically well defined separation between the two regimes exists. This allows for an investigation of the matching between the two contributions. We obtain that 0.8±0.1 of the observed mass difference is due to the light and charm quarks contribution. An estimate of the top and top-charm contributions is also given.
