In SM the left-handed neutrino is massless, and, as a matter of fact there is noright-handed counterpart. However, different neutrino experiments have acquired enough datato prove that neutrinos are massive, albeit tiny. The easiest way to generate neutrino mass isthe seesaw mechanism. In many seesaw model, the main role is played by a heavy right-handedMajorana neutrino. This also appear in other scenario of new physics as well. Currently, I havebeen studying the collider signature of heavy Majorana neutrino at LHC.Besides that, from other neutrino experiments, like MINOS, T2K, now there is strong evidenceinfavour of thethirdmixingangle, namely, θ 13 tobenon-zero. Iamcurrently alsostudyingsomenew physics model to apply on the new results on the lepton flavour violation sector, namely,µ → eγ etc, as well as to explain the non-zero value of the third mixing angles.Recently, I have worked on the collider signature of the physics of universal extra-dimension. Ihave discussed the production of heavy Kaluza-Klein (KK) electroweak gauge bosons along withheavy quarks. The prospects of LHC in this direction is discussed with center of mass energy at10 TeV as well as 14 TeV. I have also exhibited the integrated luminosity required to obtain a5σ signal as function of different parameters of the model.2
In another recent work of collider physics I have explored the discovery potential of doublycharged Higgs boson at LHC . To be specific, for a mass range of 200−1000 GeV for the doublycharged Higgs scalar, the like-sign dilepton signal can be detected at LHC at a center of massenergy 14 TeV with an integrated luminosity, say, ≥ 30fb −1 . The same analysis is also performedwith 7 TeV and 10 TeV center of mass energy cases.During the period of my doctoral work, I have worked on different aspects of new physics Beyondthe Standard Model, e.g. Grand Unified Theory, Extra-Dimensions, Supersymmetry etc. Insummary, I have explored the power law running of different coupling constants in presence ofthe TeV scale extra dimensions. How presence of the KK-excited mode of different SM-particleswill effect the running of gauge as well as Yukawa couplings are discussed.AtthetreelevelofMinimalSupersymmetricStandardModel(MSSM),thelightestneutralHiggsis lighter than the Z−boson mass. However, due to the radiative correction at the one loop level,this bound is relaxed till 135 GeV. This saved MSSM, besides the non-observation of any neutralHiggs at the LEP experiment. I have in one project addressed the same question, and discussedhow far the bound on the neutral Higgs mass could be relaxed when different KK-excited modewill appear in the loop in both five and six dimensional scenarios.I have also found distinct ways to lower the intermediate scale in the left-right supersymmetricSO(10) Grand Unified theory to explain leptogenesis as well as light left-handed neutrino masses.This way, the intermediate scale and corresponding gauge bosons will be accessible at LHC andhence the subsequent phenomenology will be discussed. I have also estimated pentaquark masseswith a proper incorporation of colour-spin symmetry for the triquark state.• Teaching summary:I have very recently joined as Assistant Professor in Physics with the BITS, Pilani, Goa campus.During this short period I have taught some part of the advance topic of particle physics andperformsomelaboratoryduties. InthecomingsemesterIhaveplannedtoteachtheintroductorycourse on Mechanics, Oscillations and Wave and some advanced topic on the course of QuantumField Theory and will have some laboratory duties as well. I have also delivered some lectureson the topic of the introduction of particle physics.3
