Study of Doubly-Charged Delta Baryons in Collisions of Copper Nuclei at the Relativistic Heavy Ion Collider
Author: Joseph J. Simpson
Publisher:
ISBN:
Category : Heavy ion collisions
Languages : en
Pages : 59
Book Description
Experiments involving heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC) produce the hottest matter known to humans, approximately 100,000 times hotter than the center of the Sun or 7 trillion degrees Celsius. In these collisions, the nucleons melt into their constituent quarks and gluons for approximately 10 yoctoseconds (1E-23 seconds). As the collision system expands and cools, the quarks and gluons combine into particles via a process called “hadronization” and subsequently stream out into the detectors. Detailed studies of these produced particles can yield information about the properties of the medium in which they were produced. Some of the produced particles, known collectively as “resonances,” have lifetimes comparable to the lifetime of the collision medium itself. More specifically, comparative studies of the relative production of short-lived resonances and possible modifications of their properties by medium effects may provide information about the conditions present in and lifetime of the collision medium. In this project, we utilize data from 24.4 million collisions of copper nuclei at center-of-mass energies of 200 GeV per nucleon pair collected by the Solenoidal Tracker At RHIC (STAR) detector to reconstruct decays of the doubly-charged Delta baryon resonance and its anti-particle. Fits to the invariant mass distribution of Delta candidates are performed as functions of transverse momentum and collision centrality and properties of the Delta resonances are extracted statistically. Specifically we look at the mass, the width, and the yield of this resonance. Comparisons of our results with previous studies from proton on proton collisions and deuteron on gold nucleus collisions, as well as with model calculations, may provide deeper insight into effects present in the collision medium as well as the lifetime of the medium itself.

Neutral Delta(1232) Production in Relativistic P+c and D+c Collisions
Author: Khusniddin K. Olimov
Publisher: LAP Lambert Academic Publishing
ISBN: 9783659750182
Category :
Languages : en
Pages : 124
Book Description
Hundreds of the discovered particles, called resonances, are produced in nucleon-nucleon, nucleon-nucleus and nucleus-nucleus collisions at high energies, when the nucleons and nuclei are accelerated (prior to collisions) to the velocities very close to the speed of light. Resonances have very short life times and decay almost instantaneously to the more stable particles, which are finally detected and measured by particle detectors. The commonly used technique for reconstruction of the mass distributions of resonances is called the method of Invariant Masses. The method of Invariant Masses, coupled with an angular criterion, for reconstruction of the mass distributions of delta0(1232) resonances and obtaining their momentum, transverse momentum, kinetic energy, emission angle and rapidity distributions was presented in detail. The history and present status of synchrophasotron and accelerator complex of JINR (Joint Institute for Nuclear Research, Dubna, Russia) were also outlined and illustrated by photos. The book can be interesting and useful for the students and young researchers in field of Nuclear and High Energy Physics and other Physics disciplines, for general knowledge.
