An estimation of the effective number of electrons contributing to the coordinate measurement with a TPC II

Makoto Kobayashi

For time projection chambers (TPCs) the accuracy in measurement of the track coordinates along the pad-row direction deteriorates with the drift distance (z): Resolution**2 = D**2…

Evidence for $π K$ -atoms with DIRAC

B. Adeva, L. Afanasyev, Y. Allkofer +77

We present evidence for the first observation of electromagnetically bound $π^{\pm} K^{\mp}$ -pairs ( $π K$ -atoms) with the DIRAC experiment at the CERN-PS. The $π K$ -atoms are produced by…

Pseudo-Dirac Scenario for Neutrino Oscillations

Makoto Kobayashi, C. S. Lim

We argue how pseudo-Dirac scenario for neutrinos leads to rich neutrino oscillation phenomena, including oscillation inside each generation. The pseudo-Dirac scenario is generalize…
