Recent results from NA61/SHINE strong interaction program.

NA61/SHINE is a multipurpose fixed-target experiment located at the CERN SPS. One of its main goals is to study the phase diagram of strongly interacting matter. For this purpose, a unique two-dimensional scan in beam momentum 13𝐴–150(8)𝐴 GeV/𝑐 and the system size, including 𝑝+𝑝, 𝑝+Pb, Be+Be, Ar+Sc, Xe+La, and Pb+Pb collisions, was performed. The main goal of the strong interaction program is to understand the onset of deconfinement and locate the critical point of strongly interacting matter. The paper reviews results from NA61/SHINE strong interaction program, focusing on hadron spectra and fluctuations in various collisions. The new results on strangeness production, particularly the ratio of positively charged kaons to pions, are also presented, including the first results for Xe+La collisions. It also reviews the recent NA61/SHINE results on proton and negatively charged hadron intermittency to search for the QCD critical point. The direct measurement of the open charm performed by NA61/SHINE is also presented. The NA61/SHINE data are compared with other experimental results and predictions from theoretical models and confronted with Power-law model predictions.
