Proton-antiproton Annihilation into Two Photons at Large S
Exclusive proton–antiproton annihilation into two photons can be viewed as the Compton process in the crossed channel. At large s (≈ 10 GeV 2) and |t|, |u| ∼ s this process can be described by a generalized partonic picture, analogous to the " soft mechanism " in wide–angle real Compton scattering. The two photons are emitted in the annihilation of a single fast quark and antiquark (" handbag g...
متن کاملMeasurement of Higgs Branching Ratio at ILC
Measurement of Higgs branching ratio is necessary to investigate Higgs coupling to particle masses. Especially, it is the most important program to measure the branching ratio of H → bb̄ and H → cc̄ at the international linear collider (ILC). We have studied the measurement accuracy of Higgs branching ratio at ILC with √ s = 250 GeV by using ZH → νν̄H events. We obtained the Higgs branching ratio ...
متن کاملRadiative proton-antiproton annihilation and isospin mixing in protonium
A detailed analysis of the radiative pp̄ annihilation is made in the framework of a two-step formalism, the pp̄ annihilates into meson channels containing a vector meson with a subsequent conversion into a photon via the vector dominance model (VDM). Both steps are derived from the underlying quark model. First, branching ratios for radiative protonium annihilation are calculated and compared wit...
متن کاملAntiproton-Hydrogen annihilation at sub-kelvin temperatures
The unique features of the LEAR (low-energy antiproton ring) facility at CERN made recently possible the synthesis of few antihydrogen atoms [1]. This effort would be pursued with the antiproton deccelerator (AD) project [2] and would make possible the storage of sensible amounts of antihydrogen. This project reinforces the already active interest to investigate several theoretical and experime...
متن کاملTracking in Antiproton Annihilation Experiments
A major ingredient of the planned new accelerator complex FAIR, to be constructed at the GSI, Darmstadt, Germany, is the availability of antiproton beams with high quality and intensity. Among the experiments which will make use of this opportunity is PANDA, a dedicated experiment to study antiproton annihilations on nucleons and nuclei. This article gives an overview on the foreseen techniques...
