Description

New results of the double spin asymmetry A1p and the spin-dependent structure function of the proton g1p as a function of $x_{Bj}$ and $Q^2$ will be presented. New COMPASS data on longitudinal polarized NH$_3$ target were collected during the year 2011 with beam of positive muons with energy E = 200 GeV}. It allows us to cover low $x$ region down to 0.025 in the range $Q^{2}>1~\mbox{GeV}/c^{2}$ for the first time.
