H+H− Pair Production at the Large Hadron Collider
We study the pair production of charged Higgs bosons at the CERN Large Hadron Collider in the context of the minimal supersymmetric extension of the standard model. We compare the contributions due to qq̄ annihilation at the tree level and gg fusion, which proceeds at one loop. At small or large values of tanβ, H+H− production proceeds dominantly via bb̄ annihilation, due to Feynman diagrams invo...
متن کاملNormalizing Weak Boson Pair Production at the Large Hadron Collider
The production of two weak bosons at the Large Hadron Collider will be one of the most important sources of SM backgrounds for final states with multiple leptons. In this paper we consider several quantities that can help normalize the production of weak boson pairs. Ratios of inclusive crosssections for production of two weak bosons and Drell-Yan are investigated and the corresponding theoreti...
متن کاملSlac-pub-391 S~com Born Corrections ~0 Wide Angle Electron Pair Production and Brexestrahlung*
I Cross sections, correct to second order, are derived for the photoproduction of wide angle electron pairs in a spherical, static, nuclear charge distribution. For typical double coincidence experiments it is found to be sufficient to treat only the convection current of the electron. The results obtained are essential to the interpretation of asymmetric electron pair production and may also b...
متن کاملCritical Schwinger Pair Production.
We investigate Schwinger pair production in spatially inhomogeneous electric backgrounds. A critical point for the onset of pair production can be approached by fields that marginally provide sufficient electrostatic energy for an off-shell long-range electron-positron fluctuation to become a real pair. Close to this critical point, we observe features of universality which are analogous to con...
متن کاملW-pair Production at Lep
We review here the measurements of W-pair production and W decay rates performed by the four LEP experiments at √ s from 161 to 209 GeV, and their relevance in support of the standard electroweak model.
