# What happens when two D-branes annihilate?

What happens when two D-branes annihilate? Do we get a radiation of strings?

D-branes usually carry charges, so either you have unstable branes (which can decay individually), or brane and anti-brane annihilating. This results in radiation of closed strings, in some cases you can even calculate the rate precisely. Or, in other words, the answer is yes. –  user566 Feb 24 '11 at 15:13
Interesting question. This scenario was considered 10 years ago in a PRD paper: Inflation from DD brane annihilation. –  user346 Feb 24 '11 at 15:21
@Hiatus: To my mind, your comment seems sufficient for an answer. –  qftme Jun 15 '11 at 14:51
