(Lunch seminar)

Brane-Antibrane Forces

Sudipta Mukherji

(I.F.T.-U.A.M.)

In perturbative string theory, for sufficiently small separation, brane-antibrane configurations suffer from instability. I will review some old (1983) and recent (1997) works which aregue that the force between branes and antibranes is non-perturbatively finite.

The almuerzo-seminario is intended to be an informal seminar and an open forum for discussion.

You are wellcome to bring your own bocata (sandwich), or coffee or tea.
