Upper limits for the production of new light gauge bosons in 0 , and 0 decays have been obtained with the Crystal Barrel detector. The kinematically well-constrained reactions pp ! 0 0 P have been studied, where P 0 ; ; 0 decays through the emission of a single photon recoiling against a missing state X. X can be a long-lived weakly interacting particle or X !. This paper gives full detail of t...

Executive Summary This white paper focuses on providing benchmarking results that highlight the Chelsio T5 performance advantage across the full range of storage networking protocols including iSCSI, iSCSI over RDMA (iSER), Windows Server 2012 SMB 3.0, Lustre over RDMA, NFS over RDMA and FCoE. Benchmarking results show T5 to be an ideal fit for high-performance storage networking solutions acro...

We study unconventional decays of the top-quark in the framework of SUSY models with spontaneously broken R-parity. In particular we discuss an effective theory which consists of the MSSM plus bilinearly broken R-parity. We demonstrate that the decay modes t → τ̃ 1 b and t → τ b̃1 can have large branching ratios even in scenarios where the tau-neutrino mass is very small. We show that existing Te...

A precise measurement of the mass of the W boson will be essential to provide improved indirect constraints, e.g. on the Higgs boson mass. Using new methods developed for this challenging measurement, the performance expected is presented, evaluating various sources of systematic uncertainties, both of experimental and theoretical nature. The focus of this contribution will be on the expectatio...

increasing the efficiency of water use is one of the main topics of sustainable agriculture in arid and semi-arid. the use of some materials such as superabsorbent polymers increase water storage in the soil and thus reduces the water use. increase water storage in the soil to reduce the effects of drought and saline soil. in order to evaluate the effect of super absorbent polymer on survival a...
