104. First Measurement of the energy dependent N* production amplitude with a Partial Wave Analysis

Hadron resonances

oral presentation

The production of hadrons with strange quarks within nuclear matter is fundamental to unravel the mystery about the content of neutron stars. A large fraction of strange hadrons are produced by resonances with broad masses that can undergo interference effects before they decay into strange hadrons.
We present here the first determination of the production amplitude of N*->p+Kaon+Lambda for...

110. Reduction of the K* meson abundance and kinetic freeze-out in heavy ion collisions

Freeze-out, hadronisation and statistical models

poster presentation

We discuss the relation between the reduction of the K* meson abundance and the kinetic freeze-out in heavy ion collisions. We evaluate the absorption cross sections of the K* meson by light mesons during the hadronic stage, and investigate effects on the K* meson abundance from both the hadronic interactions and decay of K* mesons. We show how the interplay between the interaction of the...

90. Probing the hadronic phase with resonances of different lifetimes in ALICE at the LHC

Neelima Agrawal (IIT- Indian Institute of Technology (IN))

Hadron resonances

oral presentation

The ALICE experiment has measured the production of a rich set of hadronic resonances, such as $\rho^0(770)$, K$*^0(892)$, $\phi(1020)$, $\Sigma^\pm(1385)$, $\Lambda(1520)$ and $\Xi^0(1530)$, in pp, p-Pb and Pb-Pb collisions at various energies at the LHC. A comprehensive overview and the latest results will be presented in this talk. Transverse momentum spectra, mean transverse momenta and...

136. Resonances in a sudden chemical freeze-out model

Hadron resonances

oral presentation

A chemical non-equilibrium model with a single freeze-out appeared to be rather successful in describing the LHC ALICE data at 2.76 TeV for various particles [1,2]. The pT spectra of pions, kaons, protons, $K^*(892)^0$ and the $\phi(1020)$ are described by the same hubble-like freeze-out hyper-surface that has only one parameter for the slope of the spectra – the ratio of the freeze-out time...
