  • Coleppa, Baradhwaj; Sarkar, Agnivo (Cornell University Library, 2020-11)
    We discuss the structure of a model with an extended gauge symmetry group SU(2)�SU(2)�U(1) with a correspondingly rich Electroweak Symmetry Breaking structure. In spite of the additional scalar degrees of freedom in the ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Chauhan, Bhavesh; Mohanty, Subhendra (Cornell University Library, 2018-12)
    The ANITA experiment has seen anomalous Earth emergent showers of EeV energies which cannot be explained with Standard Model interactions. On the other hand, collider tests of lepton flavor universality have shown significant ...
  • Dasgupta, Arnab; Hati, Chandan; Patra, Sudhanwa; Sarkar, Utpal (Cornell University Library, 2016-05)
    We present a minimal framework of U(1)B−L gauge extension of the Standard Model explaining dark matter abundance and matter-antimatter asymmetry simultaneously through an attractive mechanism of TeV scale WIMPy leptogenesis, ...
  • Tomar, Gaurav; Mohanty, Subhendra (arXiv, Cornell University Library, 2014-11)
    We studied an extension of the standard model with a fourth generation of fermions to explain the discrepancy in the muon (g − 2) and explain the positron excess seen in the AMS-02 experiment. We introduce a gauged SU(2)HV ...
  • Bhatt, Jitesh R.; George, Manu (Cornell University Library, 2016-08)
    We consider plasma consisting of electrons and ions in presence of a background neutrino gas and develop the magneto hydrodynamic equations for the system. We show that electron neutrino interaction can induce vorticity ...
  • Bhatt, Jitesh R.; Mishra,Hiranmaya; Singh, Balbeer (Cornell University Library, 2018-11)
    We study the effect of vorticity present in heavy ion collisions (HICs) on the temperature evolution of hot quark-gluon plasma in the presence of spin-vorticity coupling. The initial global rotation entails a nontrivial ...
  • Gowthama K. K.; Kurian, Manu; Chandra, Vinod (Cornell University Library, 2020-12)
    The electric charge transport in a weakly magnetized hot QCD medium has been investigated in the presence of an external inhomogeneous electric field. The current densities induced by the inhomogeneous electric field have ...

  • Chauhan, Bhavesh; Mohanty, Subhendra (Cornell University Library, 2018-08)
    MiniBooNe collaboration has recently reported evidence for a light sterile neutrino with large mixing angles thus corroborating the measurement by LSND twenty years ago. Such a state would be directly in conflict with ...
