Mass-degenerate Higgs bosons at 125 GeV in the Two-Higgs-Doublet Model

P. M. Ferreira, Howard E. Haber, Rui Santos +1

The analysis of the Higgs boson data by the ATLAS and CMS Collaborations appears to exhibit an excess of h --> gammaγevents above the Standard Model (SM) expectations; whereas no s…

A resource for signs and Feynman diagrams of the Standard Model

Jorge C. Romao, Joao P. Silva

When performing a full calculation within the Standard Model or its extensions, it is crucial that one utilizes a consistent set of signs for the gauge couplings and gauge fields.…

Covariant spectator quark model description of the transition

G. Ramalho, K. Tsushima

We study the transition form factors by applying the covariant spectator quark model. Using the parametrization for the baryon core wave functions as well as for…

Background subtraction and jet quenching on jet reconstruction

Liliana Apolinário, Néstor Armesto, Letícia Cunqueiro

In order to assess the ability of jet observables to constrain the characteristics of the medium produced in heavy-ion collisions at the LHC, we investigate the influence of backgr…

Octet baryon electromagnetic form factors in nuclear medium

G. Ramalho, K. Tsushima, A. W. Thomas

We study the octet baryon electromagnetic form factors in nuclear matter using the covariant spectator quark model extended to the nuclear matter regime. The parameters of the mode…

Timelike gamma* N -> Delta form factors and Delta Dalitz decay

G. Ramalho, M. T. Pena

We extend a covariant model, tested before in the spacelike region for the physical and lattice QCD regimes, to a calculation of the gamma* N -> Delta reaction in the timelike regi…
