“…An elementary particle is one of the main important branches of physics. 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].…”

In this work, the chromodynamics (QCD) theory was used to investigate the photon rate which was produced in interactions of anti-charm with gluon. The simple quantum scenario theory was implemented to give the rate equation that describes the collision of quark and gluon at a chemical potential .The photon emission rate was evaluated from the anti-charm-gluon interaction of the cg → dγ collision at the temperature of the system in the range of 180 - 360 MeV with different critical temperatures (e.g. 116.575, 139.891, 157.377 and 174.863 MeV) with photons energy GeV under the assumption that fugacity of quark and gluon are =0.08 and =0.02 respectively . The photon rate increases with decreasing the coupling of quark and gluon according to a decrease in the temperature of the system from 360 MeV to 180 MeV. The photon emission spectrum was calculated and discussed using a photon energy of 1GeV to 10GeV with different critical temperatures. In terms of QCD theory, the quantitative accomplishment was made for a unique six-flavor number nf = 4 + 2 of photon emission. The photon rate reaches minimum with photon energy E=10 GeV, it reﬂects the less coupling for the cg → dγ interaction.

“…Table (1) shows strength coupling spectra of interaction 𝑐𝑡 ̅ → 𝛾𝑔system in plasma that is calculated according to quantum flavor number, critical temperature and temperature of system. To obtain the strength coupling, the momentum spectra of system were taken from experimental date Pc =1,2,3,4 and 5 GeV [14] and elected the critical temperature Tc =150 MeV and Tc= 190MeV.It should be mentioned at this point that quantum flavor number was calculated using the summation ∑ 𝑁 6 and estimation the total electric charge of quark using ∑ 𝑒 . The strength coupling was calculated using Eq.…”

In this paper, we study flow of photons rate production in a quark-gluon QG plasma. General theory of this study is based on the field theory for hard interaction. The kinetic of photons production from hard interaction in charm with anti-top to production photons with gluon due to plasma phase at high temperatures (150, 200,250,300 and 350 MeV) .It has been investigated and studied using the postulate of quantum chromodynamic theory QCD .The photons production rate of hard photons with( GeV) are insensitive to strength coupling and depend mainly on the temperature of system T . Despite the different critical temperature (150 and 190MeV) comes, we ﬁnd that same order of flow rate photons magnitude in both cases. In both cases, the flow rate of photons production in the QG plasmais increased with increased temperature of system and photons energy and decreases with increases the strength coupling strength.

We focus in this review on the theoretical description of the probability of electron transmission at metal/semiconductor at the interface depending on the quantum theory and density functional theory .Electronic devices technology largely rely on metal/ semiconductor system interfaces, whose most important coefficient parameters for the probability of electron transmission such that :reorientation free energy , potential barrier height ( ),work function ,affinity of semiconductor ,coupling coefficient matrix element, concentration of electron ,volume of unit cell for semiconductor ,petration factor , and temperature T(K) . The probability of electron transport rate constant in Au/ Ge ,and Au/Si interface system has been calculated and the transmission through interface is examined .A Mat lab program has been used to calculate the rate constant of electron transfer and all parameters of transmission by solvingthe suitable formulas .Our results data show that the probability of the rate constant for electron transfer increases with the increasing of the coupling coefficient and temperature, and decreasing of the reorganization energy
