    Abstract: Hadron properties are studied at hot medium using the quark sigma model. The quark sigma model is extended to include eighth-order of mesonic interactions based on some aspects of quantum chromodynamic (QCD) theory. The extended effective potential tends to the original effective potential when the coupling between the higher order mesonic interact... Show More

    Abstract: α-cluster cross section production by proton/neutron induced reactions was calculated at different energies using Kalbach PRECO6 program and an analysis in the framework of pre-equilibrium exciton model made with Iwamoto-Harada [IH] model depend on pickup mechanism. Comparison with our calculation give remarkable agreement with experimental data. T... Show More

    Abstract: In optical injection locking, the light from one laser (master laser)is injected into another laser slave laser. The injected light causes changes in the slave laser characteristics, and it can lock the slave laser lasing frequency to the ML lasingfrequency. The locking characteristics are determined by theamount of injected power and thefrequency ... Show More

    Abstract: This paper explores several types of income which have not been explored so far by authors who tackled income and wealth distribution using Statistical Physics. The main types of income we plan to analyze are income before redistribution (or gross income), income of retired people (or pensions), and income of active people (mostly wages). The distr...

    Abstract: Lattice QCD with chiral fermions are extremely computationally expensive, but on the other hand provides an accurate tool for studying the physics of strong interactions. Since the truncated overlap variant of domain wall fermions are equivalent to overlap fermions in four dimensions at any lattice spacing, in this paper we have used domain wall fe... Show More
