Search for Highly Ionizing Particles in E+e-collisions at ,/i = 29 Gev*

چکیده
The results of the analysis of data taken in the continuation of a previously reported search1 for highly ionizing particles at PEP are presented. These data were taken in the period from October 1981 to June 1983. Assemblies consisting of Lexan and CR-39 plastic track detectors were exposed in two runs to integrated luminosities of 30 X 1O36 cm-2 and 150 X 10% crnw2% The search was sensitive to particles with magnetic charge 20e-5 g 5 2OOe or electric charge 3 <-2 5 180. A combined (95% G.L.) upper limit on the production cross section of d < 3.2 X lo-% cm2 is obtained, improving the limits in Ref. 1 by more than an order of magnitude. '.

In this paper, we investigate the multiplicity of charged particles in e+ e– annihilation by using different models. To achieve this we first fit the multiplicity distribution of charged particles in the energy range of 54-57 GeV by using both the Poisson distribution and KNO scaling, then we compare these results with multiplicity distribution at the lower energies. This comparison shows that...
متن کاملM ar 2 00 4 Correlation of high energy photons and charged particles in p + p and d + Au collisions at √
Azimuthal correlations between high energy photons from π decay (pγT < 10.5 GeV) and charged hadrons (p hadron T above a threshold of 2, 3 or 4 GeV/c) have been measured in p+p and d+Au collisions at √ s = 200 GeV. Clear jet-like correlations are observed at ∆φ = 0 and 180 degrees, with peak widths decreasing with increasing p T . Jet 〈jT 〉 and √ 〈k2 T 〉 in d+Au collisions are deduced from the ...
متن کاملMULTIHADRON PRODUCTION FOR e e FOR FROM 50 TO 61 GeV, C. M. ENERGIES AND COMPARISON WITH MULTIHADRON PRODUCTION IN HADRONIC INTERACTIONS
Average values of< 1- T >where T is the thrust are presented for e: e: AMY data and are compared with their values in hadronic interactions. As far as possible, similar analysis techniques have been employed in the two different interactions. Similar variation with E is observed for this average in both data. The values of < PT> and < PL > relative to the thrust axis in e e are simila...

According to the Walecka mean–field theory of nuclear interaction the collective mutual deceleration of the colliding nuclei gives rise to the bremsstrahlung of real and virtual ω– mesons. It is shown that decays of these mesons may give a noticeable contribution to the observed yields of the baryon–antibaryon pairs, dileptons and pions. Excitation functions and rapidity distributions of partic...
متن کاملNEW RESULTS FROM ASP ON SINGLE - PHOTON PRODUCTION AT , / ii = 29 GeV
u This Letter reports results of a search for radiative production by e+e-annihilation of particles that interact only weakly in matter. The search has been made in the total data set of 115 pb-l acquired with the ASP detector at ~the SLAC storage ring PEP (& = 29 GeV). No anomalous signal was observed. The number of generations of light neutrinos has been limited to NV < 7.5 (90% CL). L' rrnl ...
