  • Deppisch, Frank F.; Hati, Chandan; Patra, Sudhanwa; Sarkar, Utpal; Valle, Jose W. F. (Cornell University Library, 2016-08)
    We consider the possibility of grand unification of the SU(3)c⊗SU(3)L⊗U(1)X model in an SU(6) gauge unification group. Two possibilities arise. Unlike other conventional grand unified theories, in SU(6) one can embed the ...
  • Dey, Ujjal Kumar; Mohanty, Subhendra; Tomar, Gaurav (Cornell University Library, 2015-12)
    We explain the 750 GeV diphoton resonance in the context of the dark left-right symmetric model. A global symmetry in this model, stabilizes the dark matter and ensures that the scalar couples only to gluons and photons. ...
  • Majumder, Barun (Cornell University Library, 2013-08)
    Here we study the effects of the Generalized Uncertainty Principle in the tunneling formalism for Hawking radiation to evaluate the quantum-corrected Hawking temperature and entropy for a Schwarzschild black hole. We compare ...
  • Fairoos, C.; Ghosh, Avirup; Sarkar, Sudipta (Cornell University Library, 2017-05)
    The evolution of the black hole horizon can be effectively captured by a fictitious membrane fluid living on the stretched horizon. We show that the dynamics of this boundary matter arises from the invariance of the bulk ...
  • Kumar, Girish; Mahajan, Namit (arXiv, Cornell University Library, 2014-12)
    We calculate the zeroes of angular observables P′4 and P′5 of 4 - body angular distribution of B→K∗(→Kπ)l+l− where LHCb, in its analysis of form factor independent angular observables, has found deviations from standard ...
  • Bambhaniya, Gulab; Khan, Subrata; Konar, Partha; Mondal, Tanmoy (Cornell University Library, 2014-11)
    We consider a variant of TeV scale seesaw model in which three additional heavy right handed neutrinos are added to the standard model to generate the quasi-degenerate light neutrinos. This model is theoretically interesting ...
  • Kumar, Girish (Cornell University Library, 2016-02)
    Recently several anomalies in flavor physics have been observed and it was noticed that leptoquarks might account for the deviations from the Standard Model. In this work, we examine the effects of new physics originated ...
  • Mohanty, Subhendra; Narang, Ashish; Sadhukhan, Soumya (Cornell University Library, 2018-08)
    The non-observation of neutrinos by the IceCube at the Glashow resonance energy of 6.3 PeV has been a long standing unresolved issue. In this paper we propose a t-channel neutrino absorption by the C?B, which causes a ...
  • Bhattacharjee, Srijit; Kumar, Shailesh; Bhattacharyya, Arpan (Cornell University Library, 2020-11)
    We study the displacement memory effect and its connection with the extended-BMS symmetries near the horizon of black holes. Considering the near-horizon asymptotic metrics, we show there is a permanent shift in the geodesic ...
  • Gowthama K. K.; Kurian, Manu; Chandra, Vinod (Cornell University Library, 2021-07)
    The response of the hot QCD medium in the presence of external time dependent electromagnetic fields has been studied within the relativistic Boltzmann transport theory. The impact of the time dependence of the electromagnetic ...
  • Ghosh, Snigdha; Chandra, Vinod (Cornell University Library, 2018-08)
    The dilepton production rate in hot QCD medium is studied within a effective description of the medium in the presence of magnetic field. This could be done by obtaining the one-loop self energy of photon due to the effective ...
  • Goswami, Srubabati; K. N., Vishnudath; Khan, Najimuddin (Cornell University Library, 2018-10)
    We study the minimal type-III seesaw model in which we extend the SM by adding two SU (2) L triplet fermions with zero hypercharge to explain the origin of the non-zero neutrino masses and mixing. We show that the naturalness ...
  • Basak, Tanushree; Mohanty, Subhendra; Tomar, Gaurav (Cornell University Library, 2015-01)
    In a Dark left-right gauge model, the neutral component of right-handed lepton doublet is odd under generalized R-parity and thus the lightest one serves as the dark matter (DM) candidate. The DM in this model dominantly ...
  • Coleppa, Baradhwaj; Kumar, Satendra; Sarkar, Agnivo (Cornell University Library, 2018-08)
    Models with extra gauge symmetry are well-motivated extensions of the Standard Model. In this paper, we study an extended gauge model with a heavy neutral gauge boson Z′ which is fermiophobic. Thus, the production of such ...
  • Das, Arindam; Goswami, Srubabati; Vishnudath, K. N.; Poddar, Tanmay Kumar (Cornell University Library, 2021-04)
    We study a class of general U(1)' models to explain the observed dark matter relic abundance and light neutrino masses. The model contains three right handed neutrinos and three gauge singlet Majorana fermions to generate ...
  • Ghosh, Snigdha; Mukherjee, Arghya; Roy, Pradip; Sarkar, Sourav (Cornell University Library, 2019-01)
    The one loop self energy of the neutral rho meson is obtained for the effective ρππ and ρNN interaction at finite temperature and density in presence of a constant background magnetic field of arbitrary strength. In our ...
  • Singh, Balbeer; Abhishek, Aman; Das, Santosh K.; Mishra, Hiranmaya, (Cornell University Library, 2018-12)
    We calculate the transport coefficients, drag and momentum diffusion, of a heavy quark in a thermalised plasma of light quarks in the background of Polyakov loop. Quark thermal mass and the gluon Debye mass are calculated ...
  • Shaikh, Adiba; Kurian, Manu; Das, Santosh K.; Chandra, Vinod; Dash, Sadhana; Nandi, Basanta K. (Cornell University Library, 2021-05)
    The heavy quark drag and momentum diffusion coefficients in the presence of both the collisional and radiative processes have been studied in a hot viscous QCD medium. The thermal medium effects are incorporated by employing ...
  • Faizal, Mir; Majumder, Barun (Cornell University Library, 2014-08)
    In this paper, we will incorporation the generalized uncertainty principle into field theories with Lifshitz scaling. We will first construct both bososnic and fermionic theories with Lifshitz scaling based on generalized ...
  • Rindani, Saurabh D.; Singh, Balbeer (Cornell University Library, 2018-05)
    We examine the possibility of using single-Higgs production at an e+e− collider with polarized beams to measure, or constrain, indirectly a possible anomalous triple-Higgs coupling, which can contribute to the process via ...
