NEW RESULTS FROM ASP ON SINGLE - PHOTON PRODUCTION AT , / ii = 29 GeV

چکیده
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 't s are also placed on the masses of particles predicted to exist by models of supersymmetry.

متن کاملL-Asparaginase-producing Rouxiella Species Isolation, Antileukemia Activity Evaluation, and Enzyme Production Optimization
Background: L-Asparaginase (L-Asp) is used as an efficient anti-cancer drug, especially for acute lymphoblastic leukemia (ALL). Currently, two bacterial asparaginase isoenzymes are used for cancer treatment. Therefore, this research focused on isolating native bacteria with the ability to produce L-Asp. Materials and methods: L-Asp producing bacteria were isolated from soil samples on 9K medi...

The existence of a new massive charged gauge boson, known as W’, is proposed by many new physics scenarios. When W’ decays to tb, the final state is very similar to the final state of the s-channel single top production, where W boson is the off-shell mediator to produce the top and bottom quarks. If W’ exists, it can affect the cross section of the SM s-channel single top production, so measur...

i We present single photon annihilation results from the MARK II detector at PEP based on 100 pb-l of integrated luminosity taken at a center of mass energy fi = 29 GeV. A study of inclusive leptons for momenta 2 2 GeV/c yield the average semileptonic branching ratios of bottom (b) and charm (c) quarks and information about the b fragmentation function. A measurement of the bottom hadron lifeti...
متن کاملHigh pT Probes of Dense Matter Created in Heavy Ion Collisions at RHIC
An overview of recent high-pT hadron and photon measurements at RHIC is presented with a focus on the evolution of hadron/photon production from intermediate pT (. 5 GeV/c) to high pT (> 10 GeV/c). Addressed topics include single high-pT hadron production, azimuthal anisotropy of π production, di-jet modification at intermediate pT and inclusive photon-hadron correlations. The understanding of ...
