Third-order mixed electroweak-QCD corrections to the W-boson mass prediction from the muon lifetime
Ievgen Dubovyk, Ayres Freitas, Janusz Gluza +1
We present the calculation of the so far missing corrections to the quantity , which relates the Fermi constant to the W-boson mass, and enables pre…
Non-Standard Neutrino Interactions at Neutrino Experiments and Colliders
Ayres Freitas, Matthew Low
The impact of new physics on the interactions of neutrinos with other particles can be parametrized by a set of effective four-fermion operators called non-standard neutrino intera…
General analysis of decay chains with three-body decays involving missing energy
Chien-Yi Chen, A. Freitas
A model-independent analysis of decays of the form C -> l+ l- A (l=e,mu) is presented, including the possibility that this three-body decay is preceded by an additional decay step…
A Little Higgs Model with Exact Dark Matter Parity
A. Freitas, P. Schwaller, D. Wyler
Based on a recent idea by Krohn and Yavin, we construct a little Higgs model with an internal parity that is not broken by anomalous Wess-Zumino-Witten terms. The model is a modifi…
Distinguishing spins in decay chains with photons at the Large Hadron Collider
Wolfgang Ehrenfeld, Ayres Freitas, Ananda Landwehr +1
Several models for physics beyond the Standard Model predict new particles with a decay signature including hard photons and missing energy. Two well-motivated examples are supersy…
Consequences of T-parity breaking in the Littlest Higgs model
A. Freitas, P. Schwaller, D. Wyler
In this paper we consider the effects of the T-parity violating anomalous Wess-Zumino-Witten-Term in the Littlest Higgs model. Apart from tree level processes, the loop induced dec…
