Event-by-event analysis of ultra-relativistic heavy-ion collisions in smoothed particle hydrodynamics
The method of smoothed particle hydrodynamics (SPH) is applied for ultrarelativistic heavy-ion collisions. The SPH method has several advantages in studying event-by-event fluctuations, which attract much attention in looking for quark gluon plasma (QGP) formation, because it gives a rather simple scheme for solving hydrodynamical equations. Using initial conditions for Au+Au collisions at RHIC...
متن کاملBulk viscosity in holographic Lifshitz hydrodynamics
We compute the bulk viscosity in holographic models dual to theories with Lifshitz scaling and/or hyperscaling violation, using a generalization of the bulk viscosity formula derived in arXiv:1103.1657 from the null focusing equation. We find that only a class of models with massive vector fields are truly Lifshitz scale invariant, and have a vanishing bulk viscosity. For other holographic mode...
متن کاملEvent-by-event Physics in Relativistic Heavy-ion Collisions
Motivated by forthcoming experiments at RHIC and LHC, and results from SPS, a review is given of the present state of event-by-event fluctuations in ultrarelativistic heavy-ion collisions. Fluctuations in particle multiplicities, ratios, transverse momenta, rapidity, etc. are calculated in participant nucleon as well as thermal models. The physical observables, including multiplicity, kaon to p...
متن کاملThe influence of event attributes on tourist’s loyalty: Evidence from the Ashoura event in Yazd City
Many studies have found that the perceived authenticity of cultural and religious events affects event satisfaction and loyalty. Little is currently known about how perceived authenticity is affected by the facilities, such as food and the availability of information, which are independent determinants of satisfaction and loyalty. This study aims to examine the antecedents of event loyalty. Que...
