Modification of Z Boson Properties in Quark-Gluon Plasma
نویسندگان
چکیده
We calculate the change in the effective mass and width of a Z boson in the environment of a quark-gluon plasma under the conditions expected in Pb-Pb collisions at the LHC. The change in width is predicted to be only about 1 MeV at a temperature of 1 GeV, compared to the natural width of 2490±7 MeV. The mass shift is even smaller. Hence no observable effects are to be expected. PACS numbers: 13.38.Dg, 12.38.Mh, 25.75.-q †[email protected] ‡[email protected]

Modeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
متن کاملHypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...
متن کاملDetecting a Higgs Pseudoscalar with a Z Boson Produced in Bottom Quark Fusion
We investigate the prospects of detecting a Higgs pseudoscalar (A) in association with a Z gauge boson produced from bottom quark fusion (bb̄ → ZA) at the CERN Large Hadron Collider (LHC). A general two Higgs doublet model and the minimal supersymmetric standard model are adopted to study the discovery potential of pp → ZA → ll̄bb̄ + X, l = e or μ, via bb̄ → ZA with physics backgrounds and realisti...
متن کاملCherenkov radiations from Quark Plasma
I propose an observable to declare the formation of Quark Plasma (QP) without any doubts. It is the observation of Cherenkov photon radiations of the order of 100 MeV associated with fast light charged particles while they are penetrating hot dense mediums produced in high energy heavy ion collisions. Direct observations of Cherenkov rings associated with charged leptons decayed from Z boson or...
متن کاملQuark energy loss in an expanding quark-gluon plasma
We study the quark energy loss in an expanding quark-gluon plasma. The expanding plasma produced in high energy AA-collision is described by Bjorken’s model. The dependence of the energy loss on the infrared cutoff for the radiated gluons, on the quark mass, and on the initial conditions of QCD plasma is investigated. Study of the induced gluon radiation from a fast quark in a quark-gluon plasm...
