Initial State Radiation Physics at the B Factories
نویسنده
چکیده
A mini-review of the recent BaBar and Belle results on the process e + e − → hadrons using the initial state radiation (ISR) technique, is presented. ISR studies at the Υ(4s) resonance (B-Factories) can yield to the same observables as the low energy e + e − experiments: Precise cross-section measurements, the R ratio (ratio of cross-sections of hadron production to di-muon production) measurement, form factors measurements (from hadron pair production such as e + e − → p¯ p, Λ ¯ Λ, Λ ¯ Σ, Σ ¯ Σ), as well as J P C = 1 −− hadron spectroscopy that can lead to the discovery of new states.

متن کاملInitial state radiation effects in inclusive J/ψ production at B factories
Based on Monte Carlo techniques, we analyze the initial state radiation (ISR) effects in prompt J/ψ inclusive production at B factories. ISR enhances cross section σ(e−e+ → J/ψ+gg+X) by about 15–25%, which is almost the same size as the QCD and relativistic correction. Moreover, ISR slightly changes σ(e−e+ → J/ψ+ cc̄+X). The J/ψ momentum spectrum in e−e+ → J/ψ+gg+X and in e−e+ → J/ψ+cc̄+X is soft...
متن کاملRadiation dose to the thyroid, eyes and parotid glands of patients undergoing intra-oral radiographic procedures in a teaching hospital in Ibadan, Oyo state Nigeria
Background: Intraoral radiographs are believed to deliver low doses to patients, thus little work has been done in this regards. Considering the increment in the number of patients reporting for the examination and the probability of delayed somatic effects for accumulated low doses of X-irradiation, it is expedient to determine the doses to three critical organs eye, thyroid and parotid that a...
متن کاملLight Hadron Physics at the B Factories
We report measurements of hadronic final states produced in e+e− annihilations from the BABAR and Belle experiments. In particular, we present cross sections measured in several different processes, including two-photon physics, Initial-State Radiation, and exclusive hadron productions at center-of-mass energies near 10.58 GeV. Results are compared with theoretical predictions. Contributed to t...
متن کاملThe radiative return at φ - and B - factories : small - angle photon emission at next to leading order ⋆
The radiative return offers the unique possibility for a measurement of the cross section of electron–positron annihilation into hadrons over a wide range of energies. The large luminosity of present φand B-factories easily compensates for the additional factor of α due to the emission of a hard photon. Final states with photons at large angles can be easily identified. The rate for events with...
