Antiproton Physics

open access: yesFrontiers in Physics, 2020
We review the physics of low-energy antiprotons, and its link with the nuclear forces. This includes: antinucleon scattering on nucleons and nuclei, antiprotonic atoms, and antinucleon-nucleon annihilation into mesons.

Stability and lifetime study of carbon nanotubes as cold electron field emitters for electron cooling in the CERN extra low energy antiproton ring [PDF]

open access: diamondPhysical Review Accelerators and Beams, 2021
Electron cooling is a fundamental process to guarantee the beam quality in low energy antimatter facilities. In extra low energy antiproton, the electron cooler reduces the emittance blowup of the antiproton beam and thus delivers a focused and bright ...

Search for antiproton decay at the Fermilab Antiproton Accumulator

open access: yesThe sixth conference on the intersections of particle and nuclear physcis, 2000
A search for antiproton decay has been made at the Fermilab Antiproton Accumulator. Limits are placed on thirteen antiproton decay modes. The results include the first explicit experimental limits on the muonic decay modes of the antiproton, and the ...

Discovery of the bound state of three gluons - odderon [PDF]

open access: yesЯдерна фізика та енергетика, 2021
The TOTEM collaboration at the Large Hadron Collider, together with the D0 collaboration at the Tevatron collider at Fermilab, have announced the discovery of the odderon – a bound state of three gluons that was predicted about 50 years ago.

Probing Dense QCD Matter: Muon Measurements with the CBM Experiment at FAIR

open access: yesParticles, 2021
The Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt is designed to investigate the properties of high-density QCD matter with multi-differential measurements of hadrons and leptons ...

Ab Initio Double-Differential Ionization Cross-Section Calculations in Antiproton–Helium Collisions

open access: yesAtoms, 2023
We present ionization cross-sections for antiproton and helium collisions based on an ab initio time-dependent coupled channel method. In our calculations, a finite basis set of regular helium Coulomb wave packets and Slater function were used.

Experiments on Antiprotons: Antiproton-Nucleon CrossSections [PDF]

open access: yesPhysical Review, 1957
In this paper experiments a r e reported on annihilation and scattering of antiprotons in H{sub 2}O , D{sub 2}O, and O{sub 2}. From the data measured i t i s possible to obtain an antiproton-proton and a n antiproton-deuteron c r o s s section a t 457 Mev (lab). Further analysis gives the p-p and p-n c r o s s sections a s 104 mb for the H-p reaction c

Matter-antimatter rearrangements using the R-matrix method

open access: yesFrontiers in Physics, 2023
Antihydrogen atoms, H―, are now routinely created and can be stored for long enough to allow comparison with ordinary matter. A major goal of these efforts is to test potential physics beyond the Standard Model.

Heavy-Ion Collisions at FAIR-NICA Energies

open access: yesParticles, 2021
The “Facility for Antiproton and Ion Research” (FAIR) in Darmstadt, Germany, and the “Nuclotron-based Ion Collider Facility” (NICA) in Dubna, Russia, are two accelerator centers under construction.

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The interpretation of cosmic antiproton flux measurements from space-borne experiments is currently limited by the knowledge of the antiproton production cross-section in collisions between primary cosmic rays and the interstellar medium.
