Description :
The single spin asymmetry of charge hadron production by a 40 GeV/c proton
beam with 39% transverse polarization incident on nuclei (C, Cu) has been
measured using the Focusing Double Arm Spectrometer (FODS). The measurements
were carried out for hadrons with high Xt (82 deg. in c.m.) and with hig...

Description :
The single transverse spin asymmetry data for the charged hadron production
in pC and pCu interactions are presented. The measurements have been performed
at FODS-2 experimental setup using 40 GeV/c IHEP polarized proton beam. The
hadron transverse momentum range is from 0.5 GeV/c up to 4 GeV/c. T...

Description :
We report on the response of a prototype CMS hadron calorimeter module to
charged particle beams of pions, muons, and electrons with momenta up to 375
GeV/c. The data were taken at the H2 and H4 beamlines at CERN in 1995 and 1996.
The prototype sampling calorimeter used copper absorber plates and ...

Description :
Single-spin asymmetries for hadrons have been measured in collisions of
transversely-polarized 40 GeV/c proton beam with an unpolarized liquid hydrogen
target. The asymmetries were measured for pi+-, K+-, protons and antiprotons,
produced in the central region (0.02 < Xf < 0.10 and 0.7 < Pt < 3.4 ...

Description :
A possibility to accelerate a high intensity polarized proton beam up to 70
GeV at the IHEP accelerator, extract it from the main ring and deliver to
several experimental setups is being studied now. We propose to study a wealth
of single- and double-spin observables in various reactions using
lon...

Description :
The first stage of the proposed polarization program SPASCHARM includes the
measurements of the single-spin asymmetry (SSA) in exclusive and inclusive
reactions with production of stable hadrons and the light meson and baryon
resonances.In this study we foresee of using the variety of the unpolari...

Description :
We examine properties of t (t) over bar candidate events in lepton +jets final states to establish the helicities of W bosons in t -> W + b decays. Our analysis is based on a direct calculation of a probability density for each event to correspond to a t (t) over bar final state, as a function of th...

Description :
The standard model of particle physics contains parameters such as particle masses - whose origins are still unknown and which cannot be predicted, but whose values are constrained through their interactions. In particular, the masses of the top quark (M-t) and W boson (M-W)(1) constrain the mass of...
