DESCRIPTION:Speakers: Snezhana Komarova (Peter the Great St. Petersburg Po
 lytechnic University)\nIn recent years\, the PHENIX experiment has observe
 d collectivity in small collision systems. This behavior resembles what is
  seen in large systems where quark-gluon plasma (QGP) is produced. However
 \, whether QGP actually forms in small systems is still being debated.\n  
   This work presents measurements of the neutral pion elliptic flow ($v_2$
 ) coefficients as a function of $p_T$ for different centrality classes in 
 p+Au\, $^3$He+Au\, and p+Al collisions at 200 GeV using the event plane me
 thod. In central collisions (0-5%) for $p_T$ from 1 to 3 GeV/c\, the $v_2$
  values in $^3$He+Au exceed those in p+Au and p+Al. Moreover\, in all thre
 e collision systems\, $v_2$ values rise from central to peripheral collisi
 ons\, with larger values observed in the 40-60% centrality class.\n\nhttps
