Photon structure function revisited
Ch. Berger
The flux of papers from electron positron colliders containing data on the photon structure function ended naturally around 2005. It is thus timely to review the theoretical basis…
Flow of entropy in the evolution of the B^0 anti B^0 system: Upper bound on CP violation from unidirectionality
Ch. Berger, L. M. Sehgal
We have previously studied the time-dependence of a B anti B meson mixture in terms of its density matrix. The requirement that the absolute value of the Stokes vector zeta(t) shou…
An upper limit on CP violation in the system
Ch. Berger, L. M. Sehgal
In a previous publication we noted that the time dependence of an incoherent mixture undergoes a qualitative change when the magnitude of CP violation exceeds a…
PCAC and coherent pion production by neutrinos
Christoph Berger
Coherent pion production in low energy neutrino reactions is discussed in the framework of the partially conserved axial vector current theory (PCAC). The role of lepton mass effec…
PCAC and coherent pion production by low energy neutrinos
Ch. Berger, L. M. Sehgal
Coherent pi^+ and pi^0 production in low energy neutrino reactions is discussed in the framework of the partially conserved axial vector current theory (PCAC). The role of lepton m…
Lepton Mass Effects in Single Pion Production by Neutrinos
Ch. Berger, L. M. Sehgal
We reconsider the Feynman-Kislinger-Ravndal model applied to neutrino-excitation of baryon resonances. The effects of lepton mass are included, using the formalism of Kuzmin, Lyubu…
