Worldsheet instantons and the amplitude for string pair production in an external field as a WKB exact functional integral
Abstract We revisit the problem of charged string pair creation in a constant external electric field. The string states are massive and creation of pairs from the vacuum is a tunnelling process, analogous to the Schwinger process where charged particle-anti-particle pairs are created by an electric...
