Tests of General Relativity with GWTC-3 / LIGO Scientific Collaboration
The ever-increasing number of detections of gravitational waves (GWs) from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensitive tests of general relativity (GR) in the dynamical and strong-field regime of gravity. [...]

First joint observation by the underground gravitational-wave detector KAGRA with GEO 600 / KAGRA Collaboration
We report the results of the first joint observation of the KAGRA detector with GEO600. KAGRA is a cryogenic and underground gravitational-wave detector consisting of a laser interferometer with three-kilometer arms, and located in Kamioka, Gifu, Japan. [...]

Microscopic characterisation of photodetectors used in the hadron calorimeter of the Compact Muon Solenoid experiment / Shukla, R A (Tata Inst.) ; Achanta, V G (Tata Inst.) ; Barbaro, P De (Rochester U.) ; Dugad, S R (Tata Inst.) ; Heering, A (Notre Dame U.) ; Gupta, S K (Tata Inst.) ; Mirza, I (Tata Inst.) ; Prabhu, S S (Tata Inst.) ; Rumerio, P (Alabama U. ; CERN)
The Hybrid Photodetector (HPD) is a hybrid unit with a single accelerating gap between a common photocathode and an array of PIN diodes. Customised HPDs with 19 channels were used to detect scintillation light from hadron calorimeter in the Compact Muon Solenoid (CMS) experiment. [...]

Measurement of arrival time of particles in extensive air showers using TDC32 / Gupta, S.K (Tata Inst ; Unlisted, IN) ; Christiansen, J (CERN) ; Hayashi, Y (Osaka City U.) ; Jain, A (Tata Inst ; Unlisted, IN) ; Mohanty, P.K (Tata Inst ; Unlisted, IN) ; Ravindran, K.C (Tata Inst ; Unlisted, IN) ; Satyanarayana, B (Tata Inst ; Unlisted, IN)
Arrival time of particles in an extensive air shower (EAS) is a key physical parameter to determine its direction. EAS direction is useful for studies of anisotropy and composition of cosmic rays, and search for multi-TeV γ-rays sources. [...]

The Solar Flare of the 14th of July 2000 (L3+C detector results) / L3 Collaboration
Several experiments have reported observations on possible correlations between the flux of high energy muons and intense solar flares. If confirmed, these observations would have significant implications for acceleration processes in the heliosphere able to accelerate protons and other ions to energies of at least tens of GeV. [...]

A search for flaring Very-High-Energy cosmic-ray sources with the L3+C muon spectrometer / L3 Collaboration
The L3+C muon detector at the Cern electron-position collider, LEP, is used for the detection of very-high-energy cosmic \gamma-ray sources through the observation of muons of energies above 20, 30, 50 and 100 GeV. Daily or monthly excesses in the rate of single-muon events pointing to some particular direction in the sky are searched for. [...]

Distinguishing split supersymmetry in Higgs signals at the Large Hadron Collider / Gupta, S K ; Mukhopadhyaya, B ; Rai, S K
We examine the possibility of detecting signals of split supersymmetry in the loop-induced decay h --> gamma gamma of the Higgs boson at the Large Hadron Collider, where charginos, as surviving light fermions of the supersymmetric spectrum, can contribute in the loop. We perform a detailed study of uncertainties in various parameters involved in the analysis, and thus the net uncertainty in the standard model prediction of the rate. [...]
