BPS Bounds for Worldvolume Branes

Jerome P. Gauntlett, Joaquim Gomis, Paul K. Townsend

The worldvolume field equations of M-branes and D-branes are known to admit p-brane soliton solutions. These solitons are shown to saturate a BPS-type bound on their p-volume tensi…

Heavy charged Higgs boson decaying into top quark in the MSSM

J. A. Coarasa, David Garcia, Jaume Guasch +2

Observing a heavy charged Higgs boson produced in the near future at the Tevatron or at the LHC would be instant evidence of physics beyond the Standard Model. Whether such a Higgs…
