Measurements of higher-order cumulants of multiplicity and net-electric charge distributions in inelastic proton-proton interactions by NA61/SHINE
NA61/SHINE, :, H. Adhikary +148
This paper presents the energy dependence of multiplicity and net-electric charge fluctuations in p+p interactions at beam momenta 20, 31, 40, 80, and 158 GeV/c. Results are correc…
Evidence of isospin-symmetry violation in high-energy collisions of atomic nuclei
