A simultaneous explanation of the large phase in B_s-\bar B_s mixing and B --> ππ/ πK puzzles in R-parity violating supersymmetry
Gautam Bhattacharyya, Kalyan Brata Chatterjee, Soumitra Nandi
Recent data on meson mixings and decays are, in general, in accord with the standard model expectations, except showing a few hiccups: (i) a large phase in mixing, (ii) a…
Electroweak Symmetry Breaking and BSM Physics (A Review)
Gautam Bhattacharyya
In this talk, I shall first discuss the standard model Higgs mechanism and then highlight some of its deficiencies making a case for the need to go beyond the standard model (BSM).…
Radiative correction to the lightest neutral Higgs mass in warped supersymmetry
Gautam Bhattacharyya, Swarup Kumar Majee, Tirtha Sankar Ray
We compute radiative correction to the lightest neutral Higgs mass () induced by the Kaluza-Klein (KK) towers of fermions and sfermions in a minimal supersymmetric scenario em…
Universal Doublet-Singlet Higgs Couplings and phenomenology at the CERN Large Hadron Collider
Gautam Bhattacharyya, Gustavo C. Branco, S. Nandi
We consider a minimal extension of the standard model where a real, gauge singlet scalar field is added to the standard spectrum. Introducing the Ansatz of universality of scalar c…
CP Violation and Flavour Mixings in Orbifold GUTs
Gautam Bhattacharyya, Gustavo C. Branco, Joaquim I. Silva-Marcos
We address the flavour problem by incorporating the hypothesis of universal strength of Yukawa couplings in the framework of a 5D GUT model compactified on an $S^1/(Z_2 \times Z_2^…
Unraveling unparticles through violation of atomic parity and rare beauty
Gautam Bhattacharyya, Debajyoti Choudhury, Dilip Kumar Ghosh
We put constraints on unparticle physics, specifically on the scale $Λ_\U$ and the scale dimension $d_\U$ of unparticle operators, using (i) measurements of atomic parity violation…
