Strong interaction effects in antiprotonic atoms

Precision spectroscopy of antiprotonic atoms

Precision spectroscopy of antiprotonic atoms will be an important subject to be pursued at the new antiprotonic decelerator (AD) facility being completed at CERN. In particular, the study of antiprotonic helium atoms, peÿHe2‡ pHe‡, ®rst discovered at KEK and studied in detail at low-energy antiproton ring (LEAR), will continue to be one of the most important subjects at AD. Our recent high-reso...

Near-infrared laser spectroscopy of antiprotonic helium atoms

The ASACUSA (Atomic Spectroscopy and Collisions Using Slow Antiprotons) collaboration is currently attempting to observe a laser-induced resonant transition of antiprotonic helium atoms at wavelength of 1154.9 nm. Motivations to observe this transition and a nanosecond near-infrared laser prepared for this work are presented.

Large bandwidth excitation of Rydberg atoms in thermal vapor: Fast dynamics and strong interaction effects

SLIMP: Strong laser interaction model package for atoms and molecules

We present the SLIMP package, which provides an efficient way for the calculation of strong-field ionization rate and high-order harmonic spectra based on the single active electron approximation. The initial states are taken as single-particle orbitals directly fromoutput files of the general purpose quantumchemistry programs GAMESS, Firefly and Gaussian. For ionization, the molecular Ammosov–...

Strong Interaction Effects in Scalar Top Production

The search for supersymmetry is on the “to do” list of all experiments at currently operating or planned high energy particle colliders. It is commonly believed that hadron colliders are better suited for the search for strongly interacting sparticles (gluinos and squarks) than lepton colliders are. Hadron colliders indeed offer larger cross sections for producing such sparticles. However, expe...
