Constraining the mixing matrix for Standard Model with four generations: time dependent and semi-leptonic CP asymmetries in , and
Soumitra Nandi, Amarjit Soni
Using existing experimental information from K, B and D decays as well as electroweak precision tests and oblique parameters, we provide constraints and correlations on the paramet…
Measuring gamma in B -> K pi pi Decays
Maxime Imbeault, Nicolas Rey-Le Lorier, David London
We re-examine the question of measuring the weak phase gamma in B -> K pi pi decays. To this end, we express all B -> K pi pi amplitudes in terms of diagrams. We show that, as in B…
Diagrammatic Analysis of Charmless Three-Body B Decays
Nicolas Rey-Le Lorier, Maxime Imbeault, David London
We express the amplitudes for charmless three-body B decays in terms of diagrams. In addition, we show how to use Dalitz-plot analyses to obtain decay amplitudes which are symmetri…
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…
Measuring the Magnitude of the Fourth-Generation CKM4 Matrix Element V_{t'b'}
Diganta Das, David London, Rahul Sinha +1
We study the decays of heavy chiral (t', b') quarks in a four-generation extension of the Standard Model. If the difference between the t' and b' masses is smaller than the W mass,…
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…
