“…(13). For the NAR differential cross section there is unfortunately no experimental information, hence we calculate it following the approach pursued in [15,16] which is based on the measurement by Anderson et al of the inclusive p + p → p + X cross section at 10, 20 and 30 GeV/c incident proton momentum [54]. The tertiary contribution coming from the NAR process d + He →d + X is also included by assuming that all relevant cross sections can be obtained from the corresponding process involving a proton by multiplication by a geometrical factor 4 2/3 [16].…”

We investigate in this paper the antideuteron flux produced in high energy collisions of cosmic rays with interstellar matter. We employ a modified version of the Monte Carlo generator DPMJET-III together with the coalescence model to simulate, in an event-by-event basis, the antideuteron production in cosmic ray collisions in our Galaxy. Then, we use a diffusion model to calculate the expected flux. We find a secondary antideuteron flux at the Earth with a central value which is a factor of 2 smaller than in previous calculations, although still affected by large uncertainties due to the antideuteron production and propagation.

A new calculation of thep/p ratio in cosmic rays is compared to the recent PAMELA data. The good match up to 100 GeV allows to set constraints on exotic contributions from thermal WIMP dark matter candidates. We derive stringent limits on possible enhancements of the WIMP p flux: a mWIMP=100 GeV (1 TeV) signal cannot be increased by more than a factor 6 (40) without overrunning PAMELA data. Annihilation through the W + W − channel is also inspected and crosschecked with e + /(e − + e + ) data. This scenario is strongly disfavored as it fails to simultaneously reproduce positron and antiproton measurements.PACS numbers: 95.35.+d,98.35.Gi,11.30.Pb,95.30.Cq

High Energy Elastic Hadron-Hadron Scattering and Electromagnetic Structure of Hadron

505The differential cross section for hadron-hadron elastic scattering at high energy and the electromagnetic form factor of hadron are studied in the framework of the parton model. We calculate the electromagnetic structure function, vW 2 £H, for deep inelastic lepton-hadron scattering and use the Drell-Yan conjecture to relate it with the electromagnetic form factor of meson (baryon) which is shown to decrease as ( -t)-312(( -t)2) for large ( -t). Assuming the universal four-Fermi interaction for partons, we extend the Wu-Yang conjecture so that the differential cross sections for elastic meson-baryon and baryon-baryon scatterings for large ( -t) decrease as ( -t)-7 and ( -t)-s, respectively.
