چکیده
A beam line for electrons with energies in the range of 1 to 45 GeV, low contamination of hadrons and muons and high intensity up to 10 per accelerator spill at 27 GeV was setup at U70 accelerator in Protvino, Russia. A beam tagging system based on drift chambers with 160 μm resolution was able to measure relative electron beam momentum precisely. The resolution σp/p was 0.13% at 45 GeV where multiple scattering is negligible. This test beam setup provided a possibility to study properties of lead tungstate crystals (PbWO4) for the BTeV experiment at Fermilab. 1 corresponding author, email: [email protected] 2 deceased Preprint submitted to Elsevier Preprint 7 February 2008

For the first time, the characteristics of the charged current neutrinonuclear interactions are investigated at Eν = 1 3 GeV using the data obtained with SKAT propane-freon bubble chamber irradiated in the neutrino beam at Serpukhov accelerator. The Eν dependence of the mean multiplicities of different types of secondary particles and their multiplicity, momentum and angular distributions are m...

Data taking for Run II of the HERMES experiment will start in late 2001 with three main physics objectives for the next 4-5 years: a measurement of transversity distributions , an improved measurement of helicity distributions, and measurements of exclusive reactions to access Generalized Parton Distributions.

The investigation of e γ → ν W process is crucial for a possible high energy eγ or γγ collider since it offers the possibility for both new physics discovery and precision measurements. The polarization of the initial beam is a limiting factor for the systematic errors in both cases. This note addresses the feasibility of making a measurement of the initial electron beam polarization with relat...

Neutrino oscillations have been established in solar and atmospheric neutrinos, but a third signal from the LSND experiment is incompatible with three Standard Model neutrinos. The MiniBooNE experiment can confirm or refute the LSND oscillation signal with 1 × 10 21 protons on target. While working towards the oscillation result, MiniBooNE will accumulate more than 1 × 10 6 neutrino interaction...

This paper presents results of elliptic flow measurements at moderate high transverse momentum in Au+Au collisions using the STAR detector at RHIC. Sizable v 2 is found up to 7 GeV/c in transverse momentum. Non-flow effects are discussed comparing correlations in p+p collisions and Au+Au collisions. v 2 from two-, four-and six-particle cumulant are shown and discussed.
