عنوان	SCHWINGER EFFECT IN NONPARALLEL D1-BRANES: A PATH INTEGRAL APPROACH
نوع پژوهش	مقاله چاپ‌شده در مجلات علمی
کلیدواژه‌ها	String theory; nonparallel D1-branes; Schwinger effect
چکیده	We study the Schwinger effect in a system of nonparallel D1-branes for the bosonic strings using the path integral formalism. We drive the string pair creation rate by calculating the one-loop vacuum amplitude of the setup in presence of the background electric field defined along one of the D1-branes. We find an angle dependent minimum value for the background field and show that the decaying of vacuum into string pairs takes place for the field above this value. It is shown that in limit the vacuum becomes stable and thus no pair creation occurs.
