Demystifying the compressed top squark region with kinematic variables
Partha Konar, Tanmoy Mondal, Abhaya Kumar Swain
The ongoing perplexing scenario with no hints of new physics at the Large Hadron Collider can be elucidated amicably if the exotic particle spectrum in many of the well-motivated t…
Exploring CP phase in -lepton Yukawa coupling in Higgs decays at the LHC
Akanksha Bhardwaj, Partha Konar, Pankaj Sharma +1
We study the prospect of determining the CP violating phase in -lepton Yukawa coupling at the Large Hadron Collider (LHC). While the current run is already exploring the product…
Can nonstandard interactions jeopardize the hierarchy sensitivity of DUNE ?
K. N. Deepthi, Srubabati Goswami, Newton Nath
We study the effect of non-standard interactions (NSIs) on the propagation of neutrinos through the Earth matter and how it affects the hierarchy sensitivity of the DUNE experiment…
Qualitative observation of reversible phase change in astrochemical ethanethiol ices using infrared spectroscopy
S Pavithraa, R Rajan, P Gorai +7
Here we report the first evidence for a reversible phase change in an ethanethiol ice prepared under astrochemical conditions. InfraRed (IR) spectroscopy was used to monitor the mo…
Amplitude of solar wind density turbulence from 10--45
K. Sasikumar Raja, Madhusudan Ingale, R. Ramesh +3
We report on the amplitude of the density turbulence spectrum () and the density modulation index () in the solar wind between and . We derive t…
Pre-flare coronal jet and evolutionary phases of a solar eruptive prominence associated with M1.8 flare: SDO and RHESSI observations
Bhuwan Joshi, Upendra Kushwaha, Astrid Veronig +1
We investigate triggering, activation, and ejection of a solar eruptive prominence that occurred in a multi-polar flux system of active region NOAA 11548 on 2012 August 18 by analy…
Three-body interacting dipolar bosons and the fate of lattice supersolidity
Manpreet Singh, Tapan Mishra
We investigate a system of dipolar bosons in an optical lattice with local two and three-body interactions. Using the mean-field theory approach, we obtain the ground state phase d…

Balasubramaniam. K. M
The phenomenological study of neutral heavy gauge boson () of the minimal B-L extension was done on the dimuon production channel of the LHC. The study begins wit…
Heavy quarkonium moving in hot and dense deconfined nuclear matter
Lata Thakur, Najmul Haque, Hiranmaya Mishra
We study the behavior of the complex potential between a heavy quark and its antiquark, which are in relative motion with respect to a hot and dense medium. The heavy quark-antiqua…
Naturalness, Vacuum Stability and Leptogenesis in the Minimal Seesaw Model
Gulab Bambhaniya, P. S. Bhupal Dev, Srubabati Goswami +2
The right-handed neutrinos within the type-I seesaw mechanism can induce large radiative corrections to the Higgs mass, and naturalness arguments can then be used to set limits on…
