--Parity Violating SUSY or Leptoquarks: Virtual Effects in Dilepton Production
Gautam Bhattacharyya, Debajyoti Choudhury, K. Sridhar
In the Standard Model (SM), dilepton production in hadron--hadron collisions proceeds through the conventional Drell--Yan mechanism with the exchang…
Radiative B-decay as a test of CKM unitarity
Gautam Bhattacharyya, Gustavo C. Branco, Debajyoti Choudhury
We point out that is a sensitive probe of possible violation of CKM unitarity. We compute in a minimal extension of the Sta…
Bounds on the Masses and Couplings of Leptoquarks from Leptonic Partial Widths of the Z
Gautam Bhattacharyya, John Ellis, K. Sridhar
The vertex corrections to the leptonic partial widths of the induced by leptoquarks that couple leptons to the top quark are considered. We obtain stringent bounds on the param…
Chasing the light-gluino scenario through
Gautam Bhattacharyya, Amitava Raychaudhuri
We investigate the impact of a light gluino, which might have escaped detection at colliders, on inclusive radiative -decays mediated through penguin-like diagrams. We find that…
-- and ordinary-exotic fermion mixings revisited using some special observables
Gautam Bhattacharyya
We investigate the mixing of an extra with the standard and mixings of exotic fermions with their standard counterparts through some precisely measured electro…
