High Energy Photon-Photon Interaction at the LHC

Nuclear Physics B - Proceedings Supplements, 2008
As the LHC will be also a photon-photon collider we present the most interesting γγ processes at the LHC like production of muon pairs, W + W − as well as SUSY pairs.

Photon photon interactions

Nuclear Physics B - Proceedings Supplements, 1988
Recent results in γγ physics are presented. They include a number of new measurements of the γγ widths of members of the JPC = 0−+ and 2++ SU(3) nonets, a search for 0-+ radial excitations, studies of low mass ππ production and new results in the measurements of exclusive βc and inclusive D∗± production.

Strong photon-photon interactions

CLEO: 2014, 2014
Standard nonlinear optical materials exhibit negligible nonlinearity at the level of individual photons. I will discuss two methods to generate strong photon-photon interactions using either atom-cavity coupling, or strong interactions between atoms in Rydberg states.

Pion pair production in photon-photon interactions

Zeitschrift für Physik C Particles and Fields, 1984
The processγγπ+π− has been measured with complete particle identification. Cross-sections are presented from near threshold up to the region of thef(1270). In the mass range 0.5–0.7 GeV, crosssections are lower than the Born term predictions and show no evidence for an e(600). The two-photon width of thef(1270) is found to be in agreement with previous

Non-velocity Redshifts and Photon–Photon Interactions

Nature, 1972
RECENT data on galactic redshift anomalies have led Hoyle and Narlikar1, for example, to propose a qualitative explanation in terms of spatio-temporal variation of proper mass. The consequences of hypotheses such as this are evidently worthy of study, but there are other redshift anomalies, which should also be considered in this context.

ρ0ρ0 production in photon-photon interactions

AIP Conference Proceedings, 1989
Existing experimental data on γγ→ρ0ρ0 are reviewed. It is showed that the published results for spin‐parity composition of the cross section are not consistent with each other. A Monte‐Carlo study is performed to trace the origin of the disagreement.
