Large electroweak penguins in B --> pi pi and B --> pi K : implication for new physics
Soumitra Nandi, Anirban Kundu
We show that the anomalies in the decay channels, {\em viz.}, the large branching ratio of and large direct CP asymmetry of , can both be explaine…
Matter effects on and mesons
Vivek Kumar Tiwari, Anirban Kundu
We show how the nuclear medium affects the masses of the and mesons. The change should be easily detectable for dense matter and/or strong coupling. We also…
Semileptonic charm decay as a test for the spectator model in the -meson
Debajyoti Choudhury, Anirban Kundu, Biswarup Mukhopadhyaya
The and the quark compete with each other in decays of the -meson. We emphasize the need of obtaining reliable signals of in order to assess the merits of th…
Rho Mesons in Asymmetric Nuclear Matter: A Renormalization Group Approach
Abhee K. Dutt-Mazumder, Triptesh De, Binayak Dutta-Roy +1
The running of the couplings in presence of nuclear matter is studied, and the relevant -functions are shown to be different for and , when the nuclear me…
Advantages in Choosing Real Generators for SU(N)
A. Kundu, T. De, B. Dutta-Roy
Some results are presented indicating the distinct advantages that accrue from choosing a real representation for the generators of SU(N) rather than the usual and more popular Gel…
