Abstract
We study the higher-order anisotropy coefficients v4 and v6 in the photon and dilepton emission from a hot magnetized quark-gluon plasma. Together with the earlier predictions for v2, these results show a distinctive pattern of the anisotropy coefficients in several kinematic regimes. In the case of photon emission, nonzero coefficients vn (with even n) have opposite signs at small and large values of the transverse momentum (i.e., kT≲|eB| and kT≳|eB|, respectively). Additionally, the vn signs alternate with increasing n, and their approximate values decrease as 1/n2 in magnitude. The anisotropy of dilepton emission is well pronounced only at large transverse momenta and small invariant masses (i.e., when kT≳|eB| and M≲|eB|). The corresponding v4 and v6 coefficients are of the same magnitude and show a similar alternating sign pattern with increasing n as in the photon emission.
