CP Violation, Top Quarks and the Tevatron Upgrade
B. Grzadkowski, B. Lampe, K. J. Abraham
In order to observe a signal of possible CP violation in top-quark couplings, we study top-quark production and decay under the conditions of the Tevatron upgrade. Transverse energ…
Decay Rate and Hyperfine Structure of the bound mu+ mu- system
U. Jentschura, G. Soff, V. Ivanov +1
Results are obtained for the decay rate of ortho and para states and for the hyperfine structure of the dimuonic system mu+ mu- (dimuonium). We calculate next--to-leading order rad…
Physics with e^+e^- Linear Colliders
E. Accomando
We describe the physics potential of linear colliders in this report. These machines are planned to operate in the first phase at a center-of --mass energy of 500 GeV, bef…
Comment on "Cherenkov Radiation by Neutrinos in a Supernova Core"
Georg G. Raffelt
Mohanty and Samal have shown that the magnetic-moment interaction with nucleons contributes significantly to the photon dispersion relation in a supernova core, and with an opposit…
Resonant CP Violation in Higgs Production, Mixing and Decay
Apostolos Pilaftsis
CP violation induced by resonant transitions of a scalar to a pseudoscalar intermediate state is analyzed within a gauge-invariant resummation approach based on the pinch technique…
Resonant CP violation induced by particle mixing in transition amplitudes
Apostolos Pilaftsis
We analyze CP violation in resonant transitions involving scalar as well as fermionic intermediate states, using a gauge-invariant resummation approach implemented by the pinch tec…
