Two-pion femtoscopy in p-Pb collisions at √sN N = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report the results of the femtoscopic analysis of pairs of identical pions measured in p-Pb collisions at sNN = 5.02 TeV. Femtoscopic radii are determined as a function of event multiplicity and pair momentum in three spatial dimensions. As in the pp collision system, the analysis is complicated by the presence of sizable background correlation structures in addition to the femtoscopic signal. The radii increase with event multiplicity and decrease with pair transverse momentum. When taken at comparable multiplicity, the radii measured in p-Pb collisions, at high multiplicity and low pair t ...Daha fazlası

Charged jet cross section and fragmentation in proton-proton collisions pffiffi at s=7TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Azimuthally-differential femtoscopic measurements, being sensitive to spatio-temporal characteristics of the source as well as to the collective velocity fields at freeze out, provide very important information on the nature and dynamics of the system evolution. While the HBT radii oscillations relative to the second harmonic event plane measured recently reflect mostly the spatial geometry of the source, model studies have shown that the HBT radii oscillations relative to the third harmonic event plane are predominantly defined by the velocity fields. In this Letter, we present the first resu ...Daha fazlası

Study of the Λ–Λ interaction with femtoscopy correlations in and p–Pb collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

This work presents new constraints on the existence and the binding energy of a possible Λ-Λ bound state, the H-dibaryon, derived from Λ-Λ femtoscopic measurements by the ALICE collaboration. The results are obtained from a new measurement using the femtoscopy technique in pp collisions at s√=13 TeV and p-Pb collisions at sNN‾‾‾‾√=5.02 TeV, combined with previously published results from p-Pb collisions at s√=7 TeV. The Λ-Λ scattering parameter space, spanned by the inverse scattering length f−10 and the effective range d0, is constrained by comparing the measured Λ-Λ correlation function with ...Daha fazlası
