CP violation in photon-photon collisions

UCRHEP-T122 CP violation in photon-photon collisions.

The effective lagrangian parametrization is used to determine the CP violating effects in γγ collisions. for the processes studied the effects are found to be very small, the one exception being scalar production.

Photon-photon Collisions*

Studies of photon-photon collisions are reviewed with particular emphasis on new results reported to this conference. These include results on light meson spectroscopy and deep inelastic ey scattering. Considerable work has now been accumulated on resonance production by yy collisions. Preliminary high statistics studies of the photon structure function F$(x,Q2) are given and comments are made ...

Photon - Photon Collisions

At this meeting a huge array of new and high quality experimental results for exclusive and inclusive twophoton channels has been reported, both at high and low transverse momentum and at high and low virtual photon mass.2) In many theoretical areas the precision of QCD predictions has now been sharp ened, allowing quantitative meaSures of the running coupling constant, a8(Q2), determinations o...
