Proton-proton interactions resulting in final states with two photons are studied in a search
for the signature of flavor-changing neutral current interactions of top quarks (t) and Higgs …

The h (1 2 5) boson, discovered only in 2012, is lower than the top quark in mass, hence t→
ch search commenced immediately thereafter, with current limits at the per mille level and …

A search for flavor-changing neutral current interactions of the top quark (t) and the Higgs
boson (H) is presented. The search is based on a data sample corresponding to an …

Top flavour-changing neutral interactions with a light quark q= u, c and a gauge or Higgs
boson are very suppressed within the Standard Model (SM), but can reach observable …

Several extensions of the standard model predict associated production of dark-matter
particles with a Higgs boson. Such processes are searched for in final states with missing …

A bstract A search for flavour-changing neutral current decays of a top quark to an uptype
quark (q= u, c) and the Standard Model Higgs boson, where the Higgs boson decays …

A search is presented for the production of a single top quark via left-handed flavour-
changing neutral-current (FCNC) interactions of a top quark, a gluon and an up or charm …

We systematically calculate various flavor-changing neutral-current top-quark processes
induced by supersymmetry at the Large Hadron Collider, which include five decay modes …

A bstract A search for flavour-changing neutral-current decays of a top quark into an up-type
quark (either up or charm) and a light scalar particle X decaying into a bottom anti-bottom …
