Maths HEP Lunchtime Seminars: Semi-Bogomolny Bound for Q-Balls

Presented by Theodora Ioannidou (University of Kent at Canterbury),

6 December 2002 13:00 in CM221

"We show that many properties of the Q-balls, which have been determined numerically, can be understood in terms of analytic approximations. In particular we show that a semi-Bogomolny argument can be applied on their energy which allows the explicit derivation of the relation between the energy and the charge of the Q-balls. Moreover, numerical simulations show that the profile function of the Q-balls can be, accurately, approximated by the symmetrized Woods-Saxon distribution. "
