Physics with Ultralow-Energy Antiprotons
In this report I will describe the current status of the antiproton decelerator (AD) facility at CERN, and highlight the physics program with ultralow-energy antiproton at this installation. I then will comment on future possibilities provided higher-intensity antiproton beams become available at Fermilab, and review possibilities for initial experiments using direct degrading of high-energy an...
متن کاملPAX: Polarized Antiprotons eXperiments
Polarized antiprotons produced by spin filtering with an internal polarized gas target provide access to a wealth of single– and double–spin observables, thereby opening a window to physics uniquely accessible with the HESR at FAIR. This includes a first measurement of the transversity distribution of the valence quarks in the proton, and a first measurement of the moduli and the relative phase...
متن کاملAccelerator Possibilities for Low Energy Antiprotons at the Fermi National
There is considerable interest in the deceleration of antiprotons for particle physics, atomic physics, gravitational experiments, PET radioisotope production, antiproton capture therapy, and deep-space spacecraft propellant. The only facility in the world presently capable of producing large uxes of usable antiprotons is the Fermi National Accelerator Laboratory (FNAL). Unfortunately, at this ...
متن کاملCollisions of low-energy antiprotons and protons with atoms and molecules
Antiproton (p̄) collisions have evolved to a powerful tool for the testing of dynamic electron correlations in atoms and molecules. While advances in the understanding of p̄ collisions with the simplest oneand two-electron atoms, H and He, have been achieved experiment and theory did not agree for low-energy p̄ + He collisions (< 40 keV), stimulating a vivid theoretical activity. On the other hand...
متن کاملCollisions of low-energy antiprotons with molecular hydrogen: ionization, excitation and stopping power
A time-dependent coupled-channel approach was used to calculate ionization, excitation, and energyloss cross sections as well as energy spectra for antiproton and proton collisions with molecular hydrogen for impact energies 8<E< 4000 keV.
