R-Parity violation in B --> pi+ pi- decay
Gautam Bhattacharyya, Amitava Datta, Anirban Kundu
We consider the impact of R-parity violating suprsymmetry in the nonleptonic decay B --> pi+ pi-. This is one of the rare instances where new physics contributes to both B-Bbar mix…
Can radiative magnification of mixing angles occur for two-zero neutrino mass matrix textures?
Gautam Bhattacharyya, Amitava Raychaudhuri, Arunansu Sil
Neutrino Majorana masses and mixings can be generated from a dimension-5 operator within the standard model particle content. After a review of the mechanism of radiative enhanceme…
A general analysis with trilinear and bilinear R-parity violating couplings in the light of recent SNO data
Asmaa Abada, Gautam Bhattacharyya, Marta Losada
We analyse an extension of the minimal supersymmetric standard model including the dominant trilinear and bilinear R-parity violating contributions. We take the trilinear terms fro…
Power law enhancement of neutrino mixing angles in extra dimensions
Gautam Bhattacharyya, Srubabati Goswami, Amitava Raychaudhuri
We study the renormalization of the -type Majorana neutrino mass operator in a scenario where there is a compactified extra dimension and the fields involved correspond to on…
