The KASCADE-Grande energy spectrum of cosmic rays and the role of hadronic interaction models
(ElsevierAmsterdam, 2014-05)
Previous results obtained by KASCADE-Grande using the QGSjetII-02 hadronic interaction model have shown that the energy spectrum of cosmic rays between '10 POT. 16' eV and '10 POT. 18' eV exhibits a significant hardening ...
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 ...
KASCADE-Grande measurements of energy spectra for elemental groups of cosmic rays
(Elsevier BVAmsterdam, 2013-07)
The KASCADE-Grande air shower experiment [1] consists of, among others, a large scintillator array for measurements of charged particles, Nch, and of an array of shielded scintillation counters used for muon counting, Nµ. ...
The spectrum of high-energy cosmic rays measured with KASCADE-Grande
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The energy spectrum of cosmic rays between 10(16) eV and 10(18) eV, derived from measurements of the shower size (total number of charged particles) and the total muon number of extensive air showers by the KASCADE-Grande ...
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 ...

Transverse-momentum resummation and the spectrum of the Higgs boson at the LHC
(Elsevier Science, 2006-12)
We consider the transverse-momentum (qT) distribution of generic high-mass systems (lepton pairs, vector bosons, Higgs particles,...) produced in hadron collisions. At small qT, we concentrate on the all-order resummation ...
Ionization and double-excitations within the framework of the G-particle-hole hypervirial equation method
(John Wiley & Sons Inc, 2012-09)
Recently, through the use of one-electron excitation operators, the set of low-lying excited states of several electronic systems was obtained within the framework of the Hermitian Operator method combined with the ...
