The discovery of hadronic states with a manifestly exotic nature, 𝑃𝜓, 𝑃𝜓𝑠, 𝑇𝜓, 𝑇𝜓𝑠, and 𝑇𝜓𝜓, has given the field of spectroscopy a great boost in recent years. LHCb has been one of the major player in this field observing more than 15 exotic hadrons, thanks to its excellent detector performance which is optimized for the study of beauty and charm particles. In this talk, we will review several...
Many of the observed hadronic resonances qualify as candidate hadronic molecules. In this talk, I will discuss the features of hadronic molecules, and a survey of hadronic molecules made of a pair of heavy hadrons will be presented.
ALICE (A Large Ion Collider Experiment), one of the CERN Large Hadron Collider experiments, was originally designed to study the properties of the quark–gluon plasma (QGP), a deconfined state of quarks and gluons produced in heavy-ion collisions. The ALICE physics programme has been extended to cover a broader scope of observables related to Quantum Chromodynamics. In this overview, a...
Experimental results on the electromagnetic form factors are very useful to constrain the QCD-based theoretical models. The electron-positron collider experiments are powerful tools to study the EMFFs of various baryons in time-like via energy scan or ISR-return methods.In this talk, we will report recent progress of baryon EMFFs in time-like from various experiments, BESIII, Belle, SND and...
This presentation will open with a brief review of lattice QCD calculations showing the 2s radial excitation of the nucleon sits at ~1.9 GeV, well above the Roper resonance position. We’ll then proceed to reconcile this observation with experimental scattering data, gaining insight into the interplay between quark-model states, meson-baryon interactions and the nature of baryon...
In this talk I will review some of the recent advances that Effective Field Theories had done in hadron spectroscopy regarding exotic states. The hidden gauge formalism has been able to predict
several exotic states, like the pentaquarks, and flavour exotic states, as doubly charmed states and the recently observed $T_{cs}(2900)$. Some of these states are been also searched for in latticeQCD....
I will summarize 10 years of JPAC operations, and discuss its philosophy and future.
LHCb has collected the world's largest sample of heavy flavour hadrons. This sample is used to search for and measure the CP violation in heavy flavour decays. The latest LHCb results of CP violation in charm and beauty decays are presented, as well as prospects for future sensitivities.
The Belle II experiment at the SuperKEKB collider has been collecting asymmetric-energy electron-positron collisions at the $\Upsilon$(4S) at the world's highest intensities since 2018. A data sample comparable in size to that of predecessor experiments, collected with a novel detector and analyzed with advanced analysis techniques, provides unique or world leading results in indirect searches...
I will review lattice QCD results on spectroscopy of conventional and exotic hadrons that contain heavy quarks. These theoretical studies are particularly motivated by the experimental discoveries of exotic hadrons, most of which contain heavy quarks.
Hadrons have been understood as a quark-gluon composite state bound by the strong interactions, which is one of the interesting phenomena in the low-energy QCD. In the ordinary hadron picture, baryons and mesons are explained as a three-quark state and quark-antiquark state, respectively. In fact, nucleons (protons and neutrons) can be understood as uud and udd baryons. However, accelerator...
I will report on recent theoretical studies and ongoing work on the interpretation of exotic mesons and pentaquarks in terms of quark states or hadron molecules.
Recent achievements and perspectives on strangeness nuclear physics are presented, based mainly on experimental highlights at J-PARC. Their connection to high-density matter in neutrons stars is also discussed.
A high-quality -proton scattering experiment (J-PARC E40) successfully measured differential cross sections of ±p elastic and inelastic scattering [1,2]. They provide invaluable...
Proton spin crisis was initiated by the EMC (CERN, SPS) collaboration measurement in late 80’s which says proton spin carried by quarks far smaller than 100%. Where is the rest coming from? Yes, from gluon contribution and orbital momenta, but details still to be understood. Today, the next biggest science question is: why proton is so heavy and pion is so light? The origin of hadron masses is...
