Investigating the Proton Structure: The FAMU experiment

A. Vacchi, A. Adamczak, D. Bakalov +46

The article gives the motivations for the measurement of the hyperfine splitting (hfs) in the ground state of muonic hydrogen to explore the properties of the proton at low momentu…

Status of the detector setup for the FAMU experiment at RIKEN-RAL for a precision measurement of the Zemach radius of the proton in muonic hydrogen

R. Rossini, A. Adamczak, D. Bakalov +46

The FAMU experiment at RIKEN-RAL is a muonic atom experiment with the aim to determine the Zemach radius of the proton by measuring the 1s hyperfine splitting in muonic hydrogen. T…

Interpreting the GeV-TeV Gamma-Ray Spectra of Local Giant Molecular Clouds using GEANT4 Simulation

Abhijit Roy, Jagdish C. Joshi, Martina Cardillo +1

Recently, the Fermi-LAT gamma-ray satellite has detected six Giant Molecular Clouds (GMCs) located in the Gould Belt and the Aquila Rift regions. In half of these objects (Taurus,…

Experimental determination of the energy dependence of the rate of the muon transfer reaction from muonic hydrogen to oxygen for collision energies up to 0.1 eV

M. Stoilov, A. Adamczak, D. Bakalov +22

We report the first experimental determination of the collision-energy dependence of the muon transfer rate from the ground state of muonic hydrogen to oxygen at near-thermal energ…

Monte Carlo Simulation of CRAND Protons Trapped at Low Earth Orbits

Ritabrata Sarkar, Abhijit Roy

The Cosmic Ray Albedo Neutron Decay (CRAND) is believed to be the principal mechanism for the formation of inner proton radiation belt -- at least for relatively higher energy part…

Simulation of Cosmic Rays in the Earth's Atmosphere and Interpretation of Observed Counts in an X-ray Detector at Balloon Altitude Near Tropical Region

Ritabrata Sarkar, Abhijit Roy, Sandip K. Chakrabarti

The study of secondary particles produced by the cosmic-ray interaction in the Earth's atmosphere is very crucial as these particles mainly constitute the background counts produce…
