      True pT - dependence of A_N Status 20m

      In the just concluded unfolding analysis work, I demonstrated the unfolding of a 1-dimensional pT spectrum using singular value decomposition (TSVD) unfolding technique incorporated in the ROOT CERN package. However 1-dimensional unfolding in pT spectrum alone is expected to result in an almost flat distribution of the unfolded pT - dependence of AN, that is, this would result in very small transverse asymmetries. Thus to obtain a reasonable unfolded pT-dependence of AN distribution, we introduce 1 more dimension, the azimuthal angle (phi) distribution, giving rise to a 2-dimensional unfolding of azimuthal angle (phi) and transverse momentum (pT) distributions as the next step. So I am currently working on phi and pT 2-dimensional unfolding in readiness for true pT-dependence of AN computations.
