Phenomenology of Mirror Fermions in the Littlest Higgs Model with T-Parity
A. Freitas, D. Wyler
Little Higgs models are an interesting alternative to explain electroweak symmetry breaking without fine-tuning. Supplemented with a discrete symmetry (T-parity) constraints from e…
Collider searches and cosmology in the MSSM with heavy scalars
M. Carena, A. Freitas
In a variety of supersymmetric extensions of the Standard Model, the scalar partners of the quarks and leptons are predicted to be very heavy and beyond the reach of next-generatio…
Electroweak two-loop corrections to the effective weak mixing angle
M. Awramik, M. Czakon, A. Freitas
Recently exact results for the complete electroweak two-loop contributions to the effective weak mixing angle were published. This paper illustrates the techniques used for this co…
Determining the SUSY-QCD Yukawa Coupling
Ayres Freitas, Peter Z Skands
Among the firm predictions of softly broken supersymmetry is the identity of gauge couplings and the corresponding Yukawa couplings between gauginos, sfermions and fermions. In the…
Bosonic Corrections to The Effective Weak Mixing Angle at O(alpha^2)
M. Awramik, M. Czakon, A. Freitas
We present the complete bosonic contributions to the effective weak mixing angle, $\seff$, at the two-loop level in the electroweak interactions. We find their size to be about thr…
Scalar Top Quark Studies with Various Visible Energies
A. Sopczak, M. Carena, A. Finch +3
The precision determination of scalar top quark properties will play an important role at a future International Linear Collider (ILC). Recent and ongoing studies are discussed for…
