Constituent quark number scaling from strange hadron spectra in pp collisions at ■=13 TeV
《Chinese Physics C》2020年第1期86-98,共13页Jian-Wei Zhang Hai-Hong Li Feng-Lan Shao Jun Song 
Supported by National Natural Science Foundation of China(11575100);by Shandong Province Natural Science Foundation(ZR2019YQ06,ZR2019MA053);by A Project of Shandong Province Higher Educational Science and Technology Program(J18KA228)
We show that the p_T spectra ofΩ^-andφat midrapidity in the inelastic events in pp collisions at■=13 TeV exhibit a constituent quark number scaling property,which is a clear signal of quark combination mechanism at...
