Branching Ratios and CP Asymmetries of B Decays to a Vector and a Pseudoscalar Meson
N. G. Deshpande, B. Dutta, Sechul Oh
We consider two body decays of B meson into a light vector (V) and a pseudoscalar (P) meson. The constraint obtained from the modes on the parameter space of the input p…
A Critical Study of B Decays to Light Pseudoscalar
N. G. Deshpande, B. Dutta, Sechul Oh
Motivated by the large branching ratios observed for the process , we examine critically all the ingredients that go into estimates of B decays into two light pseu…
Impact on SUSY-Breaking Models of the -Parity Violating Squark Interpretation of the HERA Anomaly
Kingman Cheung, Duane A. Dicus, B. Dutta
The explanation of a 200 GeV R-parity violating squark to the HERA high- anomaly would have an important impact on supersymmetry-breaking models. Here we show that a squark of…
Leptoquark explanation of HERA anomaly in the context of gauge unification
N. G. Deshpande, B. Dutta
We examine the consequences of leptoquark explanation of HERA anomaly in the context of R parity conserving supersymmetric gauge unified theory with the gauge unification scale at…
Contact Interaction Explanation of HERA Events and Invariance
N. G. Deshpande, B. Dutta, Xiao-Gang He
We reexamine the contact interaction hypothesis for excess high- events seen at HERA in scattering. We consider the most general structure of contact interac…
Explaining the HERA Anomaly Without Giving Up R-parity Conservation
B. Dutta, R. N. Mohapatra, S. Nandi
We point out that in extended supersymmetric models such as supersymmetric left-right models, it is possible to have leptoquarks that explain the HERA high anomaly without gi…
