γγ cross - sections and γγ colliders 1
We summarize the predictions of different models for total γγ crosssections. The experimentaly observed rise of σγγ with √ sγγ, faster than that for σp̄p, σγp is in agreement with the predictions of the Eikonalized Minijet Models as opposed to those of the Regge-Pomeron models. We then show that a measurement of σγγ with an accuracy of / 8 − 9%(6 − 7%) is necessary to distinguish among different...
متن کامل, eγ AND γγ COLLIDERS
We calculate the cross sections for the single production of doubly-charged dileptons, both scalar and vector, at e + e − , eγ and γγ colliders at √ s = 500 GeV and 1 TeV. The eγ mode is by far the most promising – dileptons whose coupling is as weak as O(10 −4)α em can be observed, for masses virtually up to the kinematic limit. Dileptons of mass up to √ s can also be seen in e + e − and γγ co...
متن کاملCoupling at γγ Colliders
We study the constraints on the anomalous coupling gZ 5 that can be obtained from the analysis of the reaction γγ → WWZ at future linear ee colliders. We find out that a 0.5 (1) TeV ee collider operating in the γγ mode can probe values of gZ 5 of the order of 0.15 (4.5×10−2) for an integrated luminosity of 10 fb. This shows that the ability to search for this anomalous interaction of the γγ mod...
متن کاملγγ Physics at Linear Colliders
A high-energy lepton-lepton collider will give us a unique possibility to study eγ and γγ interactions at high energies. The high-energy photons can be generated by Compton back-scattering of laser light on the high-energy lepton beams. With slightly reduced luminosities for eγ and γγ collisions compared to the lepton-lepton collider one, unique and complementary studies can be performed. A lin...
متن کاملInclusive One– and Two–Jet Cross Sections in γγ Reactions at e+e− Colliders
We have calculated inclusive one– and two–jet production in photon–photon collisions superimposing direct, single resolved and double resolved cross sections for center of mass energies of the LEP1, LEP2 and NLC range. The direct and single resolved cross sections are calculated up to next–to–leading order. The double resolved two–jet cross section is calculated only in LO with a k factor estim...
