Zusammenfassung: | The NA61/SHINE experiment at the CERN SPS is a multipurpose fixed-target
spectrometer for charged and neutral hadron measurements. Its research program
includes studies of strong interactions as well as reference measurements for
neutrino and cosmic-ray physics. A significant advantage of NA61/SHINE over
collider experiments is its extended coverage of phase space available for
hadron production. This includes the nearly entire forward hemisphere for
charged hadrons and additionally, a large part of the backward hemisphere for
specific neutrals. This paper summarizes a selected set of new results,
obtained by NA61/SHINE since the last SQM conference (Busan, 2022). Particular
attention is devoted to (1) the first-ever direct measurement of open charm
production in nucleus-nucleus collisions at SPS energies (2) the difference
observed between charged and neutral meson production in Ar+Sc reactions, up to
now not understood by existing models, and (3) the importance of baseline
effects in the search for the critical point of strongly interacting matter. |
