Stability and clustering for lattice many-body quantum hamiltonians with multiparticle potentials
(SpringerNew York, 2015-11)
We analyze a quantum system of N identical spinless particles of mass m, in the
lattice Zd , given by a Hamiltonian HN = TN +VN , with kinetic energy TN ≥ 0 and potential
VN = VN,2 +VN,3 composed of attractive pair and ...
Chiral corrections in hadron spectroscopy
(1999-12-01)
We show that the implementation of chiral symmetry in recent studies of the hadron spectrum in the context of the constituent quark model is inconsistent with chiral perturbation theory. In particular, we show that the ...
Active galactic nuclei: sources for ultra high energy cosmic rays
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
Ultra high energy cosmic ray events presently show a spectrum, which we interpret here as galactic cosmic rays due to a starburst, in the radio galaxy Cen A which is pushed up in energy by the shock of a relativistic jet. ...
CENTAURUS A: THE EXTRAGALACTIC SOURCE OF COSMIC RAYS WITH ENERGIES ABOVE THE KNEE
(IOP PUBLISHING LTDBRISTOL, 2012)
The origin of cosmic rays at all energies is still uncertain. In this paper, we present and explore an astrophysical scenario to produce cosmic rays with energy ranging from below 10(15) to 3 x 10(20) eV. We show here that ...
Observation of a muon excess following a gamma-ray burst event detected at the International Space Station

A Burst with Double Radio Spectrum Observed up to 212 GHz
(Springer, 2013-06)
We study a solar flare that occurred on 10 September 2002, in active region NOAA 10105, starting around 14:52 UT and lasting approximately 5 minutes in the radio range. The event was classified as M2.9 in X-rays and 1N in ...
