Informal Pizza Seminar

Tachyons that don't bite & gluinos condensing at the CCNI

Joel Giedt

RPI

This talk is a survey of two lines of research currently spearheaded by the particle theory group at RPI, together with collaborators at other institutions. (1) An examination of negative mass-squared in mSUGRA and NUHM versions of the MSSM. In some cases (we argue), it's okay to have tachyons at the high scale! (2) Daily, 4096 CPUs grind out gluino condensation results at RPI's BlueGene/L cluster, part of the CCNI supercomputing complex (world's 7th most powerful). This computation will give, for the first time, an extrapolation of the condensate to the continuum, using domain wall lattice fermions, placing Rensselaer at the forefront of groundbreaking lattice field theory research.
