We survey the flavor-changing neutral couplings (FCNC) of the top quark predicted by some
extensions of the Standard Model: THDM, SUSY, Left–Right symmetric, TC2, 331, and …

The one-loop induced top quark decay t→ u 1 u¯ 2 u 2 (ui= u, c) is calculated in the context
of the standard model. The dominant contribution to this top quark decay arises from the …

Production of (electrically neutral) heavy-quark pairs, such as tc¯ and t¯ c, is extremely
suppressed in the SM. In supersymmetric (SUSY) theories, such as the MSSM, the number …

In this Thesis we have investigated some effects appearing in top quark and Higgs boson
decays with flavor changing neutral currents (FCNC) in the framework of generic Two Higgs …

Top quark decays are of particular interest as a mean to test the standard model (SM)
predictions, both for the dominant ($ t\to b+ W $) and rare decays ($ t\to q+ W, cV, cVV, c\phi …

This paper contains the first realistic estimate for the CMS sensitivity to Flavour Changing
Neutral Currents (FCNC) in the top quark sector. The non Standard Model decays t-> Zq and …

Flavor changing neutral currents (FCNC) decays t→ H 0+ c, t→ Z+ c, and H 0→ t+ c̄ are
discussed in the context of Alternative Left‐Right symmetric Models (ALRM) with extra …

A complete calculation of the rare three-body decay t→ chγ is presented in the framework of
the standard model. In the unitary gauge, such a calculation involves about 20 Feynman …

In this Thesis we have investigated some effects appearing in top quark and Higgs boson
decays with flavor changing neutral currents (FCNC) in the framework of generic Two Higgs …

The Standard Model (SM) of Particle Physics interactions has had great success in
describing the strong, weak and electromagnetic interactions. However, the mechanism by …
