Hadronic Resonances from STAR
Abstract. The results of resonance particle productions (ρ0, ω, K∗, φ, Σ∗, and Λ∗) measured by the STAR collaboration at RHIC from various colliding systems and energies are presented. Measured mass, width, 〈pT 〉, and yield of those resonances are reviewed. No significant mass shifts or width broadening beyond the experiment uncertainties are observed. New measurements of φ and ω from leptonic ...
متن کاملFormation time of hadronic resonances
In heavy-ion collisions, formation time of hadrons of high transverse momentum can play a pivotal role in determining the perturbative dynamics of the nal-state parton and particle system. We present methods to evaluate the formation times of light hadrons, hadronic resonances, open heavy avor and quarkonia. Experimental implications of the short formation times of heavy particles are discussed...
متن کاملResonances from a Hadronic Fireball
Production of φ(1020),Λ∗(1520) and K(892) resonances at the final stage of a heavy-ion collision is considered. It is shown that original momentum distributions and abundance of resonances formed during the process of heavy ion collision may differ significantly from their measured spectra and yields. Reconstruction probability of resonances decaying inside the fireball can be strongly suppress...
متن کاملHadronic Fluctuations and Correlations
We will provide a review of some of the physics which can be addressed by studying fluctuations and correlations in heavy ion collisions. We will discuss Lattice QCD results on fluctuations and correlations and will put them into context with observables which have been measured in heavy-ion collisions. Special attention will be given to the QCD critical point and the first order co-existence r...
متن کاملProduction cross section estimates for strongly-interacting Electroweak Symmetry Breaking Sector resonances at particle colliders
We are exploring a generic strongly-interacting Electroweak Symmetry Breaking Sector (EWSBS) with the low-energy effectie field theory for the four experimentally known particles (W L , ZL, h) and its dispersion-relation based unitary extension. In this contribution we provide simple estimates for the production cross section of pairs of the EWSBS bosons and their resonances at proton-proton co...
