SU(6), Triquark states, and the pentaquark
Swarup Kumar Majee, Amitava Raychaudhuri
The purported observation of a state with strangeness S = +1 led to its quark model interpretation in terms of a pentaquark combination involving a triquark-diquark structure…
Unraveling neutrino parameters with a magical beta-beam experiment at INO
Sanjib Kumar Agarwalla, Sandhya Choubey, Amitava Raychaudhuri
We expound in detail the physics reach of an experimental set-up in which the proposed large magnetized iron detector at the India-based Neutrino Observatory (INO) would serve as t…
Possibility of large lifetime differences in neutral B meson systems
Amol Dighe, Anirban Kundu, Soumitra Nandi
We investigate new physics models that can increase the lifetime differences in the -- systems () above their standard model values. If both as well…
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…
The neutrino mass scale and the mixing angle for quasi-degenerate Majorana neutrinos
Rathin Adhikari, Anindya Datta, Biswarup Mukhopadhyaya
Considering a general mass matrix for quasi-degenerate neutrinos and treating the experimentally known oscillation parameters as inputs, we study the correlation between the degene…
Next-to-leading-order corrections to exclusive processes in factorization
Soumitra Nandi, Hsiang-nan Li
We calculate next-to-leading-order (NLO) corrections to exclusive processes in factorization theorem, taking as an example. Partons off-shell by are consid…
