Combined effects of strong and electroweak FCNC effective operators in top quark physics at the LHC
P. M. Ferreira, R. B. Guedes, R. Santos
We study the combined effects of both strong and electroweak dimension six effective operators on flavour changing top quark physics at the LHC. Analytic expressions for the cross…
One-loop charge and colour breaking associated with the top Yukawa coupling
P. M. Ferreira
We calculate the one-loop contributions to the MSSM effective potential when the scalar top fields have non-zero vacuum expectation values and study their impact on charge and colo…
Can we build a sensible theory with broken charge and colour symmetries?
Pedro Miguel Martins Ferreira
Charge and colour symmetries are broken using the vevs of scalar fields, but it is shown the theory possesses a photon-like massless particle and electroweak interactions almost id…
Do LEP results suggest that quarks have integer electric charges?
Pedro Miguel Martins Ferreira
We argue that recent results from two-photon processes at LEP are better explained by quarks possessing integer electric charges.
One-loop stau masses in the effective potential approach
P. M. Ferreira
We calculate the one-loop contributions to the tau slepton masses in the Minimal Supersymmetric Standard Model in the effective potential approach. For the majority of parameter sp…
