Abstract
This contribution summarizes some of the main results from the LHC experiments on hadron spectroscopy and exotic states.
Highlights
According to our current understanding, the forces responsible to bind quarks into hadrons are described by the non-Abelian field theory called Quantum Chromodynamics (QCD)
A selection of results on exotic states spectroscopy at the LHC have been summarized
The LHC experiments are in a privileged position to explore the production mechanisms and spectra of the exotic states, delivering competitive results in the heavy flavor sector
Summary
According to our current understanding, the forces responsible to bind quarks into hadrons are described by the non-Abelian field theory called Quantum Chromodynamics (QCD). Considerable experimental evidence has been collected about the existence of new states, lying in the charmonium mass range, but not fitting well the charmonium mass spectrum picture[9,10,11,12,13,14,15]. Most of the observations suggested that these candidates may be exotic These studies have been performed at Babar and Belle, two experiments which took data at the e+e− Beauty Factories at SLAC (Stanford Linear Accelerator Center, USA) and KEK (High-Energy Accelerator Research Organization, Japan), respectively. Among the possible interpretations for this state currently discussed in the literature, one can remark the mesonic molecule, the hybrid meson and the tetraquark hypotesis.
