Measuring the jet azimuthal anisotropy without reconstruction of the reaction plane

The azimuthal anisotropy of jet spectra due to energy loss of jet partons in azimuthally non-symmetric volume of dense matter is considered for semi-central nuclear interactions at collider energies. We suggest a method for calculation of coefficient of jet azimuthal anisotropy without reconstruction of nuclear reaction plane considering the correlations between the azimuthal position of jet axis and the angles of particles (not incorporated in the jet). The reliability of this method in a real physical situation under LHC conditions is illustrated
