PAMELA results on the cosmic-ray antiproton flux from 60 MeV to 180 GeV in kinetic energy

, 2010
The satellite-borne experiment PAMELA has been used to make a new measurement of the cosmic-ray antiproton flux and the antiproton-to-proton flux ratio which extends previously published measurements down to 60 MeV and up to 180 GeV in kinetic energy ...

Antiproton at rest and in-flight within Intra-Nuclear Cascade Liege model (INCL) [PDF]

EPJ Web of Conferences
Antiproton-nucleus reaction is a versatile tool. It can be used to study fundamental behavior of antimatter (e.g., at CERN AD facility), neutron halo and skin of atomic nuclei (e.g., PUMA project), hyperon-antihyperon interaction (project at GSI FAIR ...

A new measurement of the antiproton-to-proton flux ratio up to 100 GeV in the cosmic radiation

, 2009
A new measurement of the cosmic ray antiproton-to-proton flux ratio between 1 and 100 GeV is presented. The results were obtained with the PAMELA experiment, which was launched into low-earth orbit on-board the Resurs-DK1 satellite on June 15th 2006 ...

Antiproton annihilation on nuclei [PDF]

AIP Conference Proceedings, 1988
A dynamical model is described for the p annihilation on nuclei. The energy transfer from the multipion system to the baryonic system is studied, as will as the response of the latter. Annihilation on two nucleons are studied and evidence for these events is searched for in experimental data.

PAMELA mission: heralding a new era in cosmic ray physics

EPJ Web of Conferences, 2014
After seven years of data taking in space, the experiment PAMELA is showing very interesting features in cosmic rays, namely in the fluxes of protons, helium, electrons, that might change our basic vision of the mechanisms of production, acceleration and

Three-dimensional parton distribution functions $g_{1T}$ and $h_{1L}^\perp$ in the polarized proton-antiproton Drell-Yan process

, 2011
We present predictions of the unweighted and weighted double spin asymmetries related to the transversal helicity distribution $g_{1T}$ and the longitudinal transversity distribution $h_{1L}^\perp$, two of eight leading-twist transverse momentum ...

Interaction of antiprotons with nuclei

, 2017
We report on self-consistent calculations of $\bar{p}$ quasi-bound states in selected nuclei performed within the relativistic mean-field (RMF) model employing $\bar{p}$ coupling constants tuned to reproduce $\bar{p}$-atom data. We confirmed considerable
