  • 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. ...
  • Ali, Ahmed Farag; Faizal, Mir; Majumder, Barun (arXiv, Cornell University Library, 2014-06)
    We will argue that the divergence in time for the asymptotic observer occurs because of specifying the position of the Horizon beyond the Planck scale. In fact, a similar divergence in time will also occur for an in-going ...
  • Suthar, Kuldeep; Roy, Arko; D. Angom (Cornell University Library, 2014-05)
    We examine the dynamics of a vortex dipole in the Bose-Einstein condensates (BECs) of trapped dilute atomic gases at zero temperature in the presence of a Gaussian barrier potential. The density-anisotropy induced by the ...
  • Sengupta, Anand (Cornell University Library, 2015-11)
    We present the results of a search for long-duration gravitational wave transients in two sets of data collected by the LIGO Hanford and LIGO Livingston detectors between November 5, 2005 and September 30, 2007, and July ...
  • Sengupta, Anand (Cornell University Library, 2016-11)
    We present the results from an all-sky search for short-duration gravitational waves in the data of the first run of the Advanced LIGO detectors between September 2015 and January 2016. The search algorithms use minimal ...
  • Sengupta, Anand (arXiv, Cornell University Library, 2013-11)
    We report on an all-sky search for periodic gravitational waves in the frequency range 50−1000Hz with the first derivative of frequency in the range −8.9×10−10 Hz/s to zero in two years of data collected during LIGO's fifth ...
  • Kumar, Girish; Mahajan, Namit (Cornell University Library, 2015-11)
    The semi-leptonic baryonic b→s decay, Λb→Λℓ+ℓ−, has been studied and new angular observables and asymmetries have been proposed which can test the presence of new physics beyond the standard model.
  • Kumar, Akash; Sengupta, Anand; Ganesh, Shashikiran (Cornell University Library, 2016-04)
    Physical Research Laboratory operates a 50cm robotic observatory at Mount Abu. This Automated Telescope for Variability Studies (ATVS) makes use of Remote Telescope System 2 (RTS2) for autonomous operations. The observatory ...
  • Hati, Chandan; Kumar, Girish; Mahajan, Namit (Cornell University Library, 2015-11)
    Recent experimental results from the LHCb, BaBar and Belle collaborations on the semitauonic decays of B meson, \bar{B}\rightarrow D^{(\ast)}\tau \bar{\nu}, showing a significant deviation from the Standard Model (SM), ...
  • Sengupta, Anand; Gaur, G. (Cornell University Library, 2016-08)
    The first direct gravitational-wave detection was made by the Advanced Laser Interferometer Gravitational Wave Observatory on September 14, 2015. The GW150914 signal was strong enough to be apparent, without using any ...
  • 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 ...
  • 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 ...
  • Sengupta, Anand (Cornell University Library, 2014-10)
    In 2009-2010, the Laser Interferometer Gravitational-wave Observa- tory (LIGO) operated together with international partners Virgo and GEO600 as a network to search for gravitational waves of astrophysical origin. The ...
  • Jamal, M.Yousuf; Mitra, Sukanya; Chandra, Vinod (Cornell University Library, 2017-01)
    Collective excitations of a hot QCD medium are the main focus of the present article. The analysis is performed within semi-classical transport theory with isotropic and anisotropic momentum distribution functions for the ...
  • Sengupta, Anand (Cornell University Library, 2016-05)
    We report on a comprehensive all-sky search for periodic gravitational waves in the frequency band 100-1500 Hz and with a frequency time derivative in the range of [−1.18,+1.00]×10−8 Hz/s. Such a signal could be produced ...
  • Bhattacharjee, Srijit; Maity, Debaprasad; Mukherjee, Rupak (Cornell University Library, 2016-04)
    We revisit the inflationary dynamics in detail for theories with Gauss-Bonnet gravity coupled to scalar functions in light of PLANCK. Considering a chaotic inflationary scenario for two models involving inflaton-Gauss-Bonnet ...
  • 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 ...
  • Sengupta, Anand (arXiv, Cornell University Library, 2013-10)
    Cosmic string cusps produce powerful bursts of gravitational waves (GWs). These bursts provide the most promising observational signature of cosmic strings. In this letter we report stringent limits on cosmic string models ...
  • 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 ...
