Study of $epen$ Collisions in the 1.5-3 Gev C.M. Energy Region Using Isr at abar | E.P.Solodov

11 Jul 2001 | Journal: | eConf C010430 (2001) T03 | Subject: | hep-ex | Abstract: | A preliminary analysis of low-energy $epen$ collision data produced via initial state radiation (ISR) has been performed using 22 $fb^{-1}$ of abar ~data. The selection of data samples corresponding to the $mumu$, $pipi$, $kk$, $p ar p$, $kkpi^0$, 3$pi$, 4$pi$, 5$pi$, 6$pi$, 7$pi$ final states accompanied by the emitted ISR hard photon has been demonstrated. The invariant mass of the hadronic final state defines the effective collision c.m. energy, and so abar ISR data can be compared to the relevant direct $epen$ measurements. The resulting distributions are already competitive with DCI and ADONE data in the 1.4-3.0 GeV energy range. In particular, they do not suffer from the relative normalization uncertainties observed for certain reactions when results from different experiments are combined. Eventually, such data may be used to measure the energy dependence of R, the ratio of the $epen o hadrons$ and $epen omumu$ cross sections, in the low-energy regime where precise measurements will have an impact on the interpretation of the new $(g-2)_{mu}$ measurements. | Source: | arXiv, hep-ex/0107027 | Services: | Forum | Review | PDF | Favorites |
