Flow Production Rate of Hard Photons Probes of Quark–Anti Quark Annihilation Processes at Plasma Phase

Abstract

The flow emission rate of hard photons from lowest order the QCD processes for quark-anti quark annihilation processes in plasma media at high temperatures (175, 200, 225, 250 and 275 MeV) have been study. In these framework photons, the flow photons emission is calculate according to quark-antiquark annihilation using the quantum chromodynamic theory and solves the ultrarelativistic equation with MATLAP program. Due to the results, we show increases flow photons rate with increases strength coupling and increases with increases temperature of media, it indicate that logarithmically divergent thermal effect on photons product. The critical temperature (Tc=155 to 195 MeV) effect on the quarks confined in hadronic matter phase, it is important parameter effect on strength coupling with flavour number. The flow photons rate spectra show decreasing with increasing th photons energy, it indicate the processes at hadronic phase.

Simple Scenario of Photons Emission from Anti Charm–Gluon Interaction using QCD Theory

“…The coupling of quark-gluon collisions at ̅ g → ̅ γ system varied at different critical temperature. As seen as from Table (2), the coupling increases with increaseing the critical temperature and increases temperature from 180 MeV to 360MeV.Figures (1) (2),( 3) and ( 4) and Tables 3),( 4),( 5)and ( 6) are shown the photon rate spectra in unit for ̅ g → ̅ γ interaction compute using the theoretical using many critical temperature 116.575 , 139.891, 157.377 and 174.863 MeV and coupling 0.4161, 0.3884, 0.3672, 0.3503, 0.3365, 0.3249 and 0.3149 in temperature of system from 180MeV to 360 MeV .In tables (3),(4),( 5) and (6) MeV in tables (3),( 4),( 5) and ( 6) respectively . In Figures (1) to (4), we can notice the rate of photon spectra in ̅ g → ̅ γ collision.…”

“…photon rate. The Coupling of quark and gluon in Table(2) was decreased with the increase of the temperature of the system from 180 MeV to 360 MeV, which was a significant influence on the rate. The coupling was decreased with the increase temperature of system in the range of 180 MeV to 360MeV for ̅ g → ̅ γ system.…”

“…It considers describing the fundamental building blocks of materials from an unbreakable component of bit small particles [1]. In recent years, the quarkgluon interaction that occurred in the heavy-ion collisions (RHIC) and large hadron collider (LHC) experiments were introduced as a valuable probing for photon production [2]. Nevertheless, the quark-gluon produced in heavy-ion collisions introduces a good understanding of the behavior of nucleons in a hadron medium [3].…”

Study of Photon Emission at High Temperature of Quark Gluon Interaction

“…According to the standard model, elementary particles are classified into fermions and bosons which the nuclear structure described through the interaction of fermions and bosons [4] [5]. Quarks are fermions introduce by George Zweig and Gell-Mann [6]. Each particle consists of a quark is known as a hadron, which is classified into mesons and baryons [7].…”

Theoretical Analysis Of The Photon Production Rate in the Quark-Gluon Interaction According To The Quantum Cromodynamic QCD Theory

“…In 2020, Ahmed M. Ashwiekh et al studied the flow rate of hard photon emission from quark-antiquark interaction at high temperatures using the lowest-order approximation of QCD theory. Results show an increase in flow rate with an increase in temperature of the media, which indicates a logarithmically divergent thermal effect on the photon product [12]. Elaf Mohammed et al in 2022 calculated and analyzed the photon rate produced from the interaction of the quark with the antiquark during the annihilation process depending on the phenomenology of QCD [13].…”
