Observing Air Showers from Cosmic Superluminal Particles

Luis Gonzalez-Mestres

The Poincaré relativity principle has been tested at low energy with great accuracy, but its extrapolation to very high-energy phenomena is much less well established. Lorentz symm…

Physics Opportunities Above the Greisen-Zatsepin-Kuzmin Cutoff: Lorentz Symmetry Violation at the Planck Scale

Luis Gonzalez-Mestres

Special relativity has been tested at low energy with great accuracy, but these results cannot be extrapolated to very high-energy phenomena: this new domain of physics may actuall…

Exclusive photoproduction of on Proton in the quark-diquark model

C. Carimalo, N. Arteaga-Romero, S. Ong

We present predictions for the exclusive photoproduction of -meson on Proton at large tranfer, where we use a quark-diquark structure model for the proton. Extrapolation from ou…

Heavy-Flavour Pentaquarks in a Chiral Constituent Quark Model

M. Genovese, J. -M. Richard, FL. Stancu +1

Within the chiral constituent quark model of Glozman and Riska, we discuss the stability of heavy pentaquarks, i.e. hadrons containing four light quarks and a heavy antiquark. The…

E. Caurier, F. Didierjean, F. Nowacki +1

Allowed branches of very proton-rich shell nuclei at the proton drip-line are calculated in the full fp valence space. The decay half-lives calculated with…

New measurement and analysis of the 7Be(p,gamma)8B cross section

F. Hammache, G. Bogaert, P. Aguer +13

Cross sections for the 7Be(p,gamma)8B reaction have been measured for E_c.m.= 0.35-1.4 MeV using radioactive 7Be targets. Two independent measurements carried out with different be…
