Collider Tests of the Little Higgs Model

Gustavo Burdman, Maxim Perelstein, Aaron Pierce

The little Higgs model provides an alternative to traditional candidates for new physics at the TeV scale. The new heavy gauge bosons predicted by this model should be observable a…

Atmospheric Neutrinos Can Make Beauty Strange

Roni Harnik, Daniel T. Larson, Hitoshi Murayama +1

The large observed mixing angle in atmospheric neutrinos, coupled with Grand Unification, motivates the search for a large mixing between right-handed strange and bottom squarks. S…

Transverse Polarization Signatures of Extra Dimensions at Linear Colliders

Thomas G. Rizzo

If significant longitudinal polarization of both the electrons and positrons becomes feasible at a future linear collider(LC), it may be possible to use spin rotators to produce tr…

Two-loop corrections to

Z. Bern, A. De Freitas, L. Dixon

An overview of the calculation of the two-loop helicity amplitudes for scattering of two gluons into two photons is presented. These matrix elements enter into the recent improved…

NNLL QCD Corrections to the Decay

A. Ghinculov, T. Hurth, G. Isidori +1

We briefly discuss the status of the NNLL QCD calculations in the inclusive rare B decay . Two important ingredients, the two-loop matrix elements of the f…
