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 ...
متن کاملPhoton - 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...
متن کاملMultiple interactions in two-photon collisions.
We compute cross sections for events where two pairs of partons scatter off each other in the same γγ reaction, giving rise to at least 3 high–pT jets. Unlike in pp̄ collisions we find the signal to lie well above the background from higher order QCD processes. If the usual “eikonaliztion” assumption is correct, the signal should be readily observable at LEP2, and might already be detectable in ...
متن کاملCoherent Photon-pomeron and Photon-photon Interactions in Ultra-peripheral Collisions at Rhic
Ultra-peripheral heavy ion collisions involve long range electromagnetic interactions at impact parameters larger than twice the nuclear radius, where no nucleonnucleon collisions occur. The first observation of coherent ρ production with and without accompanying nuclear breakup, AuAu→AuAuρ and AuAu→ AuAuρ respectively, and the observation of ee pair production AuAu→AuAuee are presented by the ...
متن کاملProbing flavor-changing top-charm-scalar interactions in e+e- collisions.
Due to the very large mass of the top-quark, probing the flavor changing top-charm-scalar vertex is clearly very important. Fortunately the largeness of mt endows a unique signature to the resulting reaction i.e., e+ea t~(fc) that should be helpfuL in identification of such events. A two Higgs doublet model, without natural flavor conservation, is used to give an illustrative estimate for the r...
