First study of the two-body scattering involving charm hadrons

KARASU UYSAL, Ayben | ALICE Collaboration

This article presents the first measurement of the interaction between charm hadrons and nucleons. The two-particle momentum correlations of pD− and pD¯ þ pairs are measured by the ALICE Collaboration in high-multiplicity pp collisions at ffiffi s p ¼ 13 TeV. The data are compatible with the Coulomb-only interaction hypothesis within ð1.1–1.5Þσ. The level of agreement slightly improves if an attractive nucleon ðNÞD strong interaction is considered, in contrast to most model predictions which suggest an overall ¯ repulsive interaction. This measurement allows for the first time an estimation of ...Daha fazlası

Measurement of anti-3 He nuclei absorption in matter and impact on their propagation in the Galaxy

KARASU UYSAL, Ayben | ALICE Collaboration

In our Galaxy, light antinuclei composed of antiprotons and antineutrons can be produced through high-energy cosmic-ray collisions with the interstellar medium or could also originate from the annihilation of dark-matter particles that have not yet been discovered. On Earth, the only way to produce and study antinuclei with high precision is to create them at high-energy particle accelerators. Although the properties of elementary antiparticles have been studied in detail, the knowledge of the interaction of light antinuclei with matter is limited. We determine the disappearance probability of ...Daha fazlası

Production of K∗(892)0 and φ(1020) in pp and Pb-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of K∗(892)0 and φ(1020) mesons in proton–proton (pp) and lead–lead (Pb–Pb) collisions at √sNN = 5.02 TeV has been measured using the ALICE detector at the Large Hadron Collider (LHC). The transverse momentum (pT) distributions of K∗(892)0 and φ(1020) mesons have been measured at midrapidity (|y| < 0.5) up to pT = 20 GeV/c in inelastic pp collisions and for several Pb–Pb collision centralities. The collision centrality and collision energy dependence of the average transverse momenta agree with the radial flow scenario observed with stable hadrons, showing that the effect is stro ...Daha fazlası
