Multi-Calorons Revisited

Atsushi Nakamula, Jun Sakaguchi

Analytic Nahm data is re-examined for SU(2) calorons, or periodic instantons, of instanton charge 2. The Nahm equations are solved analytically in terms of Jacobi elliptic function…

Systematic study of the decay rates of antiprotonic helium states

H. Yamaguchi, R. S. Hayano, T. Ishikawa +8

A systematic study of the decay rates of antiprotonic helium (\pbhef and \pbhet) at CERN AD (Antiproton Decelerator) has been made by a laser spectroscopic method. The decay rates…

Precise laser spectroscopy of the antiprotonic helium atom and CPT test on antiproton mass and charge

H. Yamaguchi, J. Eades, R. S. Hayano +8

We have measured twelve transition frequencies of the antiprotonic helium atom (pbar-He+) with precisions of 0.1--0.2 ppm using a laser spectroscopic method. The agreement between…

Hyperfine structure of antiprotonic helium revealed by a laser-microwave-laser resonance method

E. Widmann, R. S. Hayano, T. Ishikawa +9

Using a newly developed laser-microwave-laser resonance method, we observed a pair of microwave transitions between hyperfine levels of the state of antiprotonic he…

Hyperfine Structure Measurements of Antiprotonic Helium and Antihydrogen

E. Widmann, J. Eades, R. S. Hayano +8

This paper describes measurements of the hyperfine structure of two antiprotonic atoms that are planned at the Antiproton Decelerator (AD) at CERN. The first part deals with antipr…
