Long-range Correlations in Massive Jets
Abstract
We calculate the azimuthal anisotropy v2 extracted from the large y region of two particle y-φ correlations in a two-jet system, in which, the masses of the jets are not negligible compared to their energies. As the virtualities of the leading partons, initiating these jets are not negligible either, we use a recently developed, off-shell fragmentation model for the description of hadron production in the jets. We present the effect of the variation of jet mass and hadron multiplicity on the shape of the v2 curve, and reproduce the low-multiplicity data set measured in proton-proton collisions at s = 13 TeV.
