New-Physics Effects on Triple-Product Correlations in Lambda_b Decays
Wafia Bensalem, Alakabha Datta, David London
We adopt an effective-lagrangian approach to compute the new-physics contributions to T-violating triple-product correlations in charmless Lambda_b decays. We use factorization and…
B_{d,s}^0 --> K^{(*)} K-bar^{(*)}: CP phase alpha and New Physics
Alakabha Datta, David London
The decays B_{d,s}^0 --> K^{(*)} K-bar^{(*)} can be used to measure the angle alpha of the CKM unitarity triangle. The theoretical error from SU(3) breaking is expected to be small…
R-parity-violating SUSY and CP violation in B --> phi K_s
Alakabha Datta
Recent measurements of CP asymmetry in B --> phi K_S appear to be inconsistent with Standard Model expectations. We explore the effect of R-parity-violating SUSY to understand the…
Single Top Production and Extra Dimensions
Alakabha Datta
In extra dimension theories, where the gauge bosons of the standard model propagate in the bulk of the extra dimensions, there are Kaluza-Klein excitations of the standard model ga…
Non Standard mixing and the Nonleptonic B and Decays to and
Alakabha Datta, Harry J. Lipkin, Patrick J. O'Donnell
Radial mixing in the pseudoscalar systems can be generated from hyperfine interactions and annihilation terms. For the system we find the effects of r…
Measuring alpha using B -> K(*) Kbar(*) Decays
Alakabha Datta, David London
We describe a new method for obtaining the CP phase alpha via measurements of B_{d,s} -> K(*) Kbar(*) decays. This method is particularly appropriate for hadron colliders since som…
T-Violating Triple-Product Correlations in Charmless Lambda_b Decays
Wafia Bensalem, Alakabha Datta, David London
Using factorization, we compute, within the standard model, the T-violating triple-product correlations in the charmless decays Lambda_b -> F_1 F_2, where F_1 is a light spin-1/2 b…
Charmless B Decays to Final States with Radially Excited Vector Mesons
Alakabha Datta, Harry J. Lipkin, Patrick J. O'Donnell
We consider the weak decays of a B meson to final states that contain a S-wave radially excited vector meson. We consider vector-pseudoscalar final states and calculate ratios of t…
