SIDIS Single Pion Beam Spin Asymmetry measurements with CLAS 12

The CLAS12 detector at Jefferson Laboratory (JLab) started data taking with a polarized 10.6 GeV electron beam, interacting with an unpolarized liquid hydrogen target in February 2018. The collected statistics enable a high precision study of the structure function ratio F$_{\mathrm{LU}}^{\mathrm{sin\phi }}$/F$_{\mathrm{UU}}$ corresponding to the polarized electron beam spin asymmetry in semi-inclusive deep inelastic scattering. F$_{\mathrm{LU}}^{\mathrm{sin\phi }}$ is a twist-3 quantity which provides information about the quark gluon correlations in the nucleon. The contribution will present a simultaneous study of all three pion channels ($\pi^{\mathrm{+}}$, $\pi^{\mathrm{0}}$ and $\pi ^{\mathrm{-}})$ over a large kinematic range of z, x$_{\mathrm{B}}$, P$_{\mathrm{T}}$ and Q$^{\mathrm{2}}$ with virtualities Q$^{\mathrm{2}}$ ranging from 1 GeV$^{\mathrm{2\thinspace }}$up to 8 GeV$^{\mathrm{2}}$. Based on the available statistics, a fully multidimensional analysis becomes possible for the first time. The results will be compared with various model calculations.
