Exotic bottomonium hadronic transitions

Jaume Tarrús Castellà

We report on a recent computation of the transitions of exotic bottomonium to standard bottomonium and light quark hadrons. We work under the assumption that the and $Υ(…

Doubly heavy baryons in Born-Oppenheimer EFT

Jaume Tarrús Castellà

We report on the recent progress on the computation of the doubly heavy baryon spectrum in effective field theory. The effective field theory is built upon the heavy-quark mass and…

Effective QCD string and doubly heavy baryons

Joan Soto, Jaume Tarrús Castellà

Expressions for the potentials appearing in the nonrelativistic effective field theory description of doubly heavy baryons are known in terms of operator insertions in the Wilson l…

Line shape and the experimental determination of the branching fraction

Jorge Segovia, Jaume Tarrús Castellà

We study the photon spectrum line-shape of the decay process in a nonrelativistic effective field theory (EFT) framework of quantum chromodynamics (QCD). We tak…

Nonrelativistic effective field theory for heavy exotic hadrons

Joan Soto, Jaume Tarrús Castellà

We propose an effective field theory to describe hadrons with two heavy quarks without any assumption on the typical distance between the heavy quarks with respect to the typical h…

Effective field theory for double heavy baryons at strong coupling

Joan Soto, Jaume Tarrús Castellà

We present an effective field theory for doubly heavy baryons that goes beyond the compact heavy diquark approximation. The heavy-quark distance is only restricted to $m_Q\gg 1…
