A note on dimension-5 operators in GUTs and their impact
Joydeep Chakrabortty, Amitava Raychaudhuri
Quantum gravity or string compactification can lead to effective dimension-5 operators in Grand Unified Theories which modify the gauge kinetic terms. We exhaustively discuss the g…
Universal extra dimension: Violation of Kaluza-Klein parity
Biplob Bhattacherjee
The minimal Universal Extra Dimension (mUED) model respects the Kaluza-Klein (KK) parity , where is the KK number. However, it is possible to have interactions located…
Probing two Universal Extra Dimension model with leptons and photons at the LHC and ILC
Kirtiman Ghosh
We discuss the collider signatures of electroweak (1,0)-mode excitations in the framework of two universal extra dimension (2UED) at the LHC and ILC. In general, pair production of…
Neutrino mass and low-scale leptogenesis in a testable SUSY SO(10) model
Swarup Kumar Majee, Mina K. Parida, Amitava Raychaudhuri
It is shown that a supersymmetric SO(10) model extended with fermion singlets can accommodate the observed neutrino masses and mixings as well as generate the desired lepton asymme…
Universal Extra Dimension
Anirban Kundu
This is a brief discussion of the following features of the Universal Extra Dimension (UED) model: (i) Formulation, (ii) Indirect bounds, (iii) Collider search and the Inverse Prob…
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…
