Study of the optical-discharge plasma in multicomponent mixtures of molecular gases

Abstract

We study path integrals over reparametrizations of the world-sheet boundary. Such integrals arise when string propagates between fixed space-time contours. In gauge/string duality they are needed to describe gauge theory Wilson loops. We show that (1) in AdS/CFT, the integral is well defined and gives a finite 1-loop correction to the Wilson loop; (2) in critical string theory, the integral is UV divergent, and fixed contour amplitudes are off shell. In the second case, we show that the divergences can be removed by renormalizing the contour. We calculate the 2-loop contour β-function and explain how it is related to the D0-brane effective action. We also apply this method to compute the first α correction to the effective action of higher dimensional branes.

Effect of radiation refraction on the characteristics of a cw optical discharge

“…The continuous optical discharge supported by a CO 2 -laser radiation was extensively studied in the last quarter of last century. At the present time, these studies are continued at the new stage [1] when a possibility was shown of effective synthesis of diamond coating using a continuous optical discharge in the laser plasmatron mode [2]. One of the main characteristic of an optical discharge in this mode is the threshold power of laser radiation that is necessary to maintain the discharge in the dependence on the gas flow rate.…”
