Аннотация
The effect of parton distributions on
-meson production in
,
,
, and
He
Au collisions at the c.m. reaction energy of
GeV is studied. The results of the PHENIX experiment are compared with their counterparts calculated by means of the PYTHIA generator using various sets of parton distributions (PYTHIA/Angantyr, PYTHIA
CTEQ15, and PYTHIA
EPPS16). Apart from nuclear modifications of parton distributions, an additional physics mechanism might have an effect on
-meson production in
He
Au collisions.
