چکیده
The data on mT spectra of K 0 S , K + and K− mesons produced in p+p and p+p interactions in the energy range √ sNN = 4.7 − 1800 GeV are compiled and analyzed. The spectra are parameterized as dN mT dmT = C · e −mT /T . The values of the inverse slope parameter T for K s , K + and K− are similar. The T parameter increases monotonically with √ sNN from T ≈ 130 MeV at √ sNN = 4.7 GeV to T ≈ 220 MeV at sNN = 1800 GeV. The T parameter measured in p+p (p+p) is significantly lower than the corresponding parameter obtained for central Pb+Pb collisions. The anomalous energy dependence of T observed for Pb+Pb collisions is not seen in the case of p+p interactions.

The results on transverse mass spectra of Λ hyperons produced in all inelastic p+p and p+p interactions in the energy range √ sNN = 3.6 − 1800 GeV are compiled and analyzed. The energy dependence of the mean transverse mass and the inverse slope parameter of the spectra is presented and discussed. These results should be used as a reference in the study of Λ hyperon production in nuclear collis...

The data on mT spectra of K 0 S , K + and K− mesons produced in all inelastic p+p and p+p interactions in the energy range √ sNN = 4.7 − 1800 GeV are compiled and analyzed. The spectra are parameterized by a single exponential function, dN mT dmT = C · e −mT /T , and the inverse slope parameter T is the main object of study. The T parameter is found to be similar for K s , K + and K− mesons. It...

Results are presented on π ± , K ± , and p transverse mass spectra and particle multiplic-ity ratios at mid-rapidity in Au+Au collisions at √ s NN =130 and 200 GeV and in p+p collisions at √ s=200 GeV. Comparisons are made to results from lower energies. The bulk properties of the collision inferred from these results are discussed. New states in which the nucleon mass vanishes or quarks and gl...

We found that the experimental results on transverse mass spectra of kaons produced in central Pb+Pb (Au+Au) interactions show an anomalous dependence on the collision energy. The inverse slopes of the spectra increase with energy in the low (AGS) and high (RHIC) energy domains, whereas they are constant in the intermediate (SPS) energy range. We argue that this anomaly is probably caused by a ...
متن کاملDeuteron-Nucleus Collisions in a Multi-Phase Transport Model
Using a multi-phase transport (AMPT) model, we study pseudo-rapidity distributions and transverse momentum spectra in deuteron-gold collisions at RHIC. We find that final-state partonic and hadronic interactions affect the transverse momentum spectrum of protons more than those of kaons or pions. Relative to p+p collisions at same center-of-mass energy per nucleon pair, the effect of final-stat...
