Sigma to p mu+ mu-: Standard Model or New Particle?
G. Valencia
The HyperCP collaboration observed three events for the decay Sigma to p mu+ mu-. They suggested that new physics may be required to understand the implied decay rate and the obser…
The Decay Omega^- -> Xi^- pi^+ pi^- in Chiral Perturbation Theory
Oleg Antipin, Jusak Tandean, G. Valencia
We study the decay Omega^- -> Xi^- pi^+ pi^- in heavy-baryon chiral perturbation theory. At leading order, the decay is completely dominated by the Xi^{*0}(1530) intermediate state…
Probing Quartic Couplings Through Three Gauge Boson Production at an Linear Collider
S. Dawson, A. Likhoded, G. Valencia +1
We explore the capability of a 500 or 1000 GeV linear collider to measure anomalous quartic gauge boson couplings. In the framework of a non-linear effective Lagrangian wi…
Theoretical Aspects of CP Violation in Hyperon Decays
G. Valencia
I review the estimate of the CP violating asymmetry within the standard model. I then review the estimate of the upper bound on this asymmetry that arises from measureme…
Probing Anomalous Gauge Boson Couplings at LEP
S. Dawson, G. Valencia
We bound anomalous gauge boson couplings using LEP data for the partial widths. We use an effective field theory formalism to compute the one-loop co…
