I will review the current status of meson spectroscopy, with particular focus on exotic candidates. I will discuss the theory and analysis tools that are commonly used to calculate the spectrum and to compare with data, both in the light and heavy sector.
A vast number of new hadrons have been discovered in recent years, a large proportion of them by Belle and LHCb. Many of these new hadronic states do not fit into the traditional quark model, and their nature is yet to be understood. Progress in this field requires advances both in theory and experiment. This contribution presents recent results in heavy hadron spectroscopy from Belle II and LHCb.
Recently, numerous excited states have been observed in heavy hadron decays and beam experiments, with some interpreted as exotic candidates beyond the traditional three-quark model. In this talk, I will provide a brief overview of the recent progress in strange baryon spectroscopy and introduce a new experiment utilizing a GeV-photon beam at SPring-8/LEPS2.
Photoproduction of hadrons is an important experimental tool to understand the generation of hadrons as bound systems of quarks and gluons in the non-perturbative regime of QCD. The GlueX experiment, which is located in Hall D of Jefferson Lab, uses an intense photon beam with energies of up to 12 GeV that is incident on a liquid hydrogen target. A large acceptance spectrometer with...
The Facility for Antiproton and Ion Research (FAIR) in Darmstadt has begun installing accelerator components and will soon begin commissioning. The main driving synchrotron the SIS100 will provide a wide range of beams, including an intense proton beam with up to 30 GeV/c. Currently, the physics potential to expand the program of the CBM detector to include measuring exclusive final states...
An introduction on the study of exclusive processes in hadron-hadron colliders will be given. This will be followed by results of measurements of exclusive processes at the LHC. Where applicable, parallels with measurements in lepton-hadron interactions will be highlighted.
In my talk, I will focus on the problem of model dependency affecting the phenomenology of generalized parton distributions (GPDs). I will argue that a lot of useful information on nucleon structure can already be accessed from the amplitudes of exclusive processes, particularly thanks to recently developed techniques based on Froissart-Gribov projections. Another way to avoid model dependency...
Measuring Deeply Virtual Compton Scattering (DVCS) on the neutron is one of the necessary steps to understand the structure of the nucleon in terms of Generalized Parton Distributions (GPDs). Neutron targets play a complementary role to transversely polarized proton targets in the determination of the GPD E. This poorly known and poorly constrained GPD is essential to obtain the contribution...
