A Facility for Low-energy Antiproton and Ion Research

open access: yes, 2004
The future accelerator facility for beams of ions and antiprotons at Darmstadt will provide antiproton beams of intensities that are two orders of magnitude higher than currently available. Within the foreseen scheme, antiprotons can be decelerated to 30

Search for antiproton decay at the Fermilab antiproton accumulator

open access: yesPhysical Review Letters, 1994
A search for antiproton decay has been made at the Fermilab antiproton accumulator. Limits are placed on five antiproton decay modes. At the 95% C.L. we find that [tau][sub [ital [bar p]]]/[ital B]([ital [bar p]][r arrow][ital e][sup [minus]][gamma])[gt]1848 yr, [tau][sub [ital [bar p]]]/[ital B]([ital [bar p]][r arrow][ital e][sup 0][pi][sup 0])[gt ...

Extracting Kinetic Freeze‐Out Properties in High‐Energy Collisions Using a Multisource Thermal Model

open access: yesAdvances in High Energy Physics, Volume 2024, Issue 1, 2024.
We study the transverse momentum (pT) spectra of neutral pions and identified charged hadrons produced in proton–proton (pp), deuteron–gold (d–Au), and gold–gold (Au–Au) collisions at the center of mass energy sNN=200 GeV. The study is made in the framework of a multisource thermal model used in the partonic level.

Production of Λc+ hypernuclei in antiproton–nucleus collisions

open access: yesPhysics Letters B, 2017
We investigate the production of charm-baryon hypernucleus OΛc+16 in the antiproton–O16 collisions within a fully covariant model that is based on an effective Lagrangian approach.

Recent Developments from ASACUSA on Antihydrogen Detection

open access: yesEPJ Web of Conferences, 2018
The ASACUSA Collaboration at CERNs Antiproton Decelerator aims to measure the ground state hyperfine splitting of antihydrogen with high precision to test the fundamental symmetry of CPT (combination of charge conjugation, parity transformation, and time

Antiprotons from Dark Matter: Effects of a Position-Dependent Diffusion Coefficient

open access: yes, 2011
Energetic antiprotons in cosmic rays can serve as an important indirect signature of dark matter. Conventionally, the antiproton flux from dark matter decays or annihilations is calculated by solving the transport equation with a space-independent ...

Simulation of AntiMatter–Matter Interactions in Geant4

open access: yesEPJ Web of Conferences, 2018
Cross sections of antiproton and antinucleus interactions with nuclei are calculated using stochastic averaging method. A new implementation of the Quark-Gluon-String Model (QGSM) is proposed for simulation of multi-particle production in antinucleus ...

Properties of quark matter produced in heavy ion collision

open access: yes, 2005
We describe the hadronization of quark matter assuming that quarks creating hadrons coalesce from a continuous mass distribution. The pion and antiproton spectrum as well as the momentum dependence of the antiproton to pion ratio are calculated.

Antimatter from supersymmetric dark matter [PDF]

open access: yes, 2000
We propose low-energy antideuterons in cosmic rays as a new possible signature for indirect detection of supersymmetric dark matter. Since the energy spectrum of the antiproton secondary component is still spoilt by considerable theoretical ...
