A bstract We review and revise the phenomenology of the scalar portal—a new scalar
particle with the mass in GeV range that mixes with the Higgs boson. In particular, we …

A bstract We carry out an exploratory study of the isospin one a 0 (980) and the isospin one-
half κ scalar mesons using N f= 2+ 1+ 1 Wilson twisted mass fermions at one lattice spacing …

Investigation of light and heavy tetraquark candidates using lattice QCD Page 1 Journal of
Physics: Conference Series OPEN ACCESS Investigation of light and heavy tetraquark …

We consider the effective interaction of quarks with a new GeV-scale vector particle that
couples to electroweak gauge bosons by the so-called effective Chern–Simons (CS) …

In this thesis I study heavy spin effects in the bbud tetraquark system with quantum numbers
I (JP)= 0 (1−). In my approach I use antistatic-antistatic-light-light potentials calculated from …

We study the light scalar mesons a_0 (980) and kappa using N_f= 2+ 1+ 1 flavor lattice
QCD. In order to probe the internal structure of these scalar mesons, and in particular to …
