First results on angular distributions of thermal dileptons in nuclear collisions

NA60 Collaboration, R. Arnaldi, K. Banicz +50

The NA60 experiment at the CERN SPS has studied dimuon production in 158A GeV In-In collisions. The strong excess of pairs above the known sources found in the complete mass region…

Nuclear electron capture rate in stellar interiors and the case of 7Be

P. Quarati, A. M. Scarfone

Nuclear electron capture rate from continuum in an astrophysical plasma environment (like solar core) is calculated using a modified Debye-Huckel screening potential and the relate…

Exploring the transverse spin structure of the nucleon

Umberto D'Alesio

We discuss our present understanding of the transverse spin structure of the nucleon and of related properties originating from parton transverse motion. Starting from the transver…

$ϕ$ Meson Production in In-In Collisions and the $ϕ$ Puzzle

Michele Floris

The NA60 experiment measured dimuon production in In-In collisions at 158 AGeV. This paper presents a high statistics measurement of $ϕ \to μμ$ with the specific objective to provide…

Doubly special relativity and translation invariance

S. Mignemi

We propose a new interpretation of doubly special relativity (DSR) based on the distinction between the momentum and the translation generators in its phase space realization. We a…

Instability of hyper-compact Kerr-like objects

Vitor Cardoso, Paolo Pani, Mariano Cadoni +1

Viable alternatives to astrophysical black holes include hyper-compact objects without horizon, such as gravastars, boson stars, wormholes and superspinars. The authors have recent…

Near-horizon limit of the charged BTZ black hole and AdS_2 quantum gravity

Mariano Cadoni, Mohammad R. Setare

We show that the 3D charged Banados-Teitelboim-Zanelli (BTZ) black hole solution interpolates between two different 2D AdS spacetimes: a near-extremal, near-horizon AdS_2 geometry…

Analytical predictions of non-Gaussian distribution parameters for stellar plasmas

A. M. Scarfone, P. Quarati, G. Mezzorani +1

Stimulated by the recent debate on the physical relevance and on the predictivity of q-Gaussian formalism, we present specific analytical expressions for the parameters characteriz…

Sivers Effect for Pion and Kaon Production in Semi-Inclusive Deep Inelastic Scattering

M. Anselmino, M. Boglione, U. D'Alesio +5

We study the Sivers effect in the transverse single spin asymmetries (SSA) for pion and kaon production in semi-inclusive deep inelastic scattering (SIDIS) processes. We perform a…

Leading order analysis of neutrino induced dimuon events in the CHORUS experiment

The CHORUS Collaboration

We present a leading order QCD analysis of a sample of neutrino induced charged-current events with two muons in the final state originating in the lead-scintillating fibre calorim…

Geometry of plane sections of the infinite regular skew polyhedron {4,6|4}

Roberto De Leo, Ivan A. Dynnikov

The asymptotic behavior of open plane sections of triply periodic surfaces is dictated, for an open dense set of plane directions, by an integer second homology class of the three-…
