Radiative correction of the correlator for 1 − + light hybrid
نویسندگان
چکیده
We calculate the radiative corrections to the current-current correlator of the hybrid current g ¯ q(x)γ ν iG a µν T a q(x). Based on this new result we use the QCD sum rule approach to estimate lower bounds on the masses of the J P C =1 −+ and 0 ++ light hybrids.

Investigation of the Effect of Recombination on Superluminescent Light-Emitting Diode Output Power Based on Nitride Pyramid Quantum Dots
In this article, the temperature behavior of output power of superluminescent light-emitting diode (SLED) by considering the effect of non-radiative recombination coefficient, non-radiative spontaneous emission coefficient and Auger recombination coefficients has been investigated. For this aim, GaN pyramidal quantum dots were used as the active region. The numerical method has been used to sol...
متن کاملComputer generated complex filter for an all optical and a digital optical hybrid correlator
We present results of a correlation filter utilising a computer generated hologram using an analogue ferroelectric liquid crystal spatial light modulator (SLM). The SLM amplitude modulates light and can induce a 0/π phase shift, which is equivalent to modulating along the real axis. Two pixels are combined into a macropixel using a phase detour technique enabling full complex modulation. The me...
متن کاملComputational Study of Radiative and Convective Heat Transfer in a Cylindrical Combustion Chamber
In this paper, the effect of cold air on the fluid flow inside the cylindrical combustion chamber and its wall temperature distribution have been studied computationally, taking into account the effect of radiative heat transfer from hot gases. The results have been compared with the case that radiative heat transfer was neglected. It is observed that the reattachment length increases when incr...
