Title: Results on transverse spin asymmetries in the polarized proton-proton elastic scattering in the CNI region at STAR

Abstract

Elastic scattering of polarized protons at small four momentum transfer squared t is described by interference of Coulomb and nuclear amplitudes. Coulomb amplitude is well calculable by QED and such interference provides a unique opportunity to study the nuclear amplitude. At high energies this amplitude is believed to be dominated by Pomeron exchange. Measurement of asymmetries can provide evidence for contribution of other Reggeons, including hypothetical Odderon. Polarized proton collider at RHIC facility is a perfect place for such experiment.A one-week dedicated run with special beam optics in June 2009 allowed us to collect statistics of more than 30 millions of elastic triggers with transversely polarized beams in the -t range 0.005-0.035 (GeV/c){sup 2} at {radical}(s) = 200 GeV. In this paper we present preliminary results of single and double transverse spin asymmetries.
