Constraints on the Four-Generation Quark Mixing Matrix from a Fit to Flavor-Physics Data
Ashutosh Kumar Alok, Amol Dighe, David London
In the scenario with four quark generations, we perform a fit using flavor-physics data and determine the allowed values -- preferred central values and errors -- of all of the ele…
Neutral Gauge Boson Contributions to the Dimuon Charge Asymmetry in B Decays
Ashutosh Kumar Alok, Seungwon Baek, David London
Recently, the D0 Collaboration measured the CP-violating like-sign dimuon charge asymmetry in neutral B decays, finding a 3.2sigma difference from the standard-model (SM) predictio…
New Physics in b -> s mu+ mu-: CP-Conserving Observables
Ashutosh Kumar Alok, Alakabha Datta, Amol Dighe +3
We perform a comprehensive study of the impact of new-physics operators with different Lorentz structures on decays involving the b -> s mu+ mu- transition. We examine the effects…
SM with four generations: Selected implications for rare B and K decays
Amarjit Soni, Ashutosh Kumar Alok, Anjan Giri +2
We extend our recent work and study implications of the Standard Model with four generations (SM4) for rare B and K decays. We again take seriously the several 2-3 anomalies se…
