“…On the other hand, the different modelling has been questioned by striking agreement of the p+p data with other predictions of statistical and hydrodynamical modelsmean multiplicities of hadrons and transverse mass spectra at low and intermediate p T follow a similar pattern. Moreover, recent LHC data on the azimuthal angle distribution of charged particles in high multiplicity p+p interactions [11][12][13] show anisotropies up to now observed only in heavy-ion collisions and attributed to the hydrodynamical expansion of matter [14]. Also it was reported that relative strange particle yields in p+p interactions at LHC smoothly increase with increasing charged particle multiplicity and for high multiplicity collisions are close to those in Pb+Pb collisions [15].…”

The NA61/SHINE experiment at the CERN SPS is performing a uniqe study of the phase diagram of strongly interacting matter by varying collision energy and nuclear mass number of colliding nuclei. In central Pb+Pb collisions the NA49 experiment found structures in the energy dependence of several observables in the CERN SPS energy range that had been predicted for the transition to a deconfined phase. New measurements of NA61/SHINE find intriguing similarities in p+p interactions for which no deconfinement transition is expected at SPS energies. Possible implications will be discussed.

“…It was reported that relative strange hadron yields in p+p interactions at LHC smoothly increase with increasing charged-particle multiplicity and for high multiplicity interactions are close to those in Pb+Pb collisions [39]. Moreover, recent LHC data on the azimuthal angle distribution of charged particles in high multiplicity p+p interactions [40][41][42] show anisotropies up to the recently observed only in heavy-ion collisions and attributed to the hydrodynamical expansion of matter [43]. This suggests that QGP may also be produced in p+p interactions at the LHC energies, at least in collisions with sufficiently high hadron multiplicity.…”

Many new particles, mostly hadrons, are produced in high-energy collisions between atomic nuclei. The most popular models describing the hadron-production process are based on the creation, evolution and decay of resonances, strings or quark–gluon plasma. The validity of these models is under vivid discussion, and it seems that a common framework for this discussion is missing. Here, for the first time, we explicitly introduce the diagram of high-energy nuclear collisions, where domains of the dominance of different hadron-production processes in the space of laboratory-controlled parameters, the collision energy and nuclear-mass number of colliding nuclei are indicated. We argue that the recent experimental results suggest the location of boundaries between the domains, allowing for the first time to sketch an example diagram. Finally, we discuss the immediate implications for experimental measurements and model development following the proposed sketch of the diagram.
