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…
Extra-dimensional relaxation of the upper limit of the lightest supersymmetric neutral Higgs mass
Gautam Bhattacharyya, Swarup Kumar Majee, Amitava Raychaudhuri
The upper limit on the mass of the lightest CP-even neutral Higgs in the minimal supersymmetric standard model is around 135 GeV for soft supersymmetry breaking masses in the 1 TeV…
