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 m...

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...

We present the results of a search for high energy extraterrestrial neutrinos with the Baikal underwater Cherenkov detector NT200, based on data taken in 1998 2003. Upper limits on the diffuse fluxes of νe + νμ + ντ , predicted by several models of AGN-like neutrino sources, are derived. For an E−2 behavior of the neutrino Preprint submitted to Elsevier Science 5 February 2008 spectrum, our lim...
