Query: The Schwinger pair production rate in confining theories via holography   We study the Schwinger pair production in confining theories. The production
rate in an external electric field E is numerically evaluated by using the
holographic description. There exist two kinds of critical values of the
electric field, i) E=E_c, above which there is no potential barrier and
particles are freely generated, ii) E=E_s, below which the confining string
tension dominates the electric field and the pair production does not occur. We
argue the universal exponents associated with the critical behaviors.
