Measurement of Cosmic Ray antiproton/proton flux ratio at TeV energies with ARGO-YBJ
Extensive Air Showers Cosmic Rays Moon shadow antiproton ARGO-YBJ
2011/10/10
Cosmic ray antiprotons provide an important probe for the study of cosmic-ray propagation in the interstellar space and to investigate the existence of Galactic dark matter. The ARGO-YBJ experiment, l...
Monte Carlo simulations of neutron-rich matter of relevance to the inner neutron-star crust are performed for a system of A=5,000 nucleons. To determine the proton fraction in the inner crust, numeric...
Space-time variation of the electron-to-proton mass ratio in a Weyl model
Space-time variation the electron-to-proton mass ratio
2011/1/13
We consider a phenomenological model where the effective fermion masses depend on the local value of Weyl tensor as a possible explanation for the recent data indicating a space-time variation of the...

2010/3/9
Previous surveys in a few metal-poor Globular Clusters (GCs) showed that the determination of abundances for Li and proton-capture elements offers a key tool to address the intra-cluster pollution sce...
