Resumo

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.
