With the discovery of new states in recent years, interest in spectroscopy has revived. Recent experimental results in heavy flavour spectroscopy are reviewed, including charmonium, bottomonium, charmed mesons and baryons and bottom mesons.
In this talk, we review the most recent progress in the searching for the exotic hadrons, including hybrids, multi-quark states, molecules and so on. We only focus on the studies with a charmonium and one or more light mesons in the final…
We highlight the STAR experiment's recent measurements on electromagnetic and hard probes of nuclear collisions, which inform the field's understanding of these physical phenomena and by extension QCD. Results on vector meson production…
We present a summary of recent and older results on Bessel integrals and their relation with zeta numbers.
During the past year many interesting results were published in heavy quark baryon spectroscopy. In addition to several refined measurements, new states were directly observed both in the charm and the bottom sector. In this paper we review…
We describe the recent experiments which claimed an observation of a tetra-neutron signal. Production reactions like transfer, knockout, fragmentation or photodisintegration have been used at very different experiments and facilities to…
In this survey article, we report some new results of Gr\"obner-Shirshov bases, including new Composition-Diamond lemmas and some applications of some known Composition-Diamond lemmas.
In this paper I present the most recent results of the ongoing searches, mainly from Tevatron Collider experiments, for new physics beyond the Standard Model. While no signal has been seen so far, many analyses are reaching the point in…
New results on elastic (exclusive) production of vector mesons are presented, mainly on J/\psi and phi mesons with emphasis on an interpretation of the data within pQCD.
Three recent results from the ATLAS experiment at the LHC are presented. A new excited heavy meson state is observed through its hadronic transition to the ground state. The production cross-section of B+ mesons is measured as a function of…
In this contribution I review recent experimental developments in the spectroscopy of higher-mass mesons, especially candidate radial excitations discussed at the WHS99 meeting in Frascati.
In this talk I summarize the capability of future lepton colliders to indirectly discover a new $Z'$ and to determine its couplings to the fermions of the Standard Model. The physics associated with sitting on the $Z'$-pole is also briefly…
The experimental status of the excited $D_s^+$ mesons is reviewed with particular emphasis on the most recent findings related to the $D^*_{s1}(2860)$ and $D^*_{s3}(2860)$ resonances. It is shown that the list of experimental results…
The measurements of B_s mesons and b baryons advanced greatly in the past year. The ground state b baryon Xi_b^0 was observed for the first time; numerous decay modes of the B_s^0 and b baryons were newly seen; measurements of CP violation…
The past decades witnessed the golden era of hadron physics. Many excited open heavy flavor mesons and baryons have been observed since 2017. We shall provide an updated review of the recent experimental and theoretical progresses in this…
Searches for new physics using muons are reviewed. Particular attention is paid to muon number non-conserving processes, like the decay muon-->e+gamma and muon-electron conversion in muonic atoms. Also, experimental determinations and…
The quark model was formulated in 1964 to classify mesons as bound states made of a quark-antiquark pair, and baryons as bound states made of three quarks. For a long time all known mesons and baryons could be classified within this scheme.…
Current measurements of isospin splittings in mesons and baryons are sufficiently precise that they allow estimates of the mass difference between constituent up and down quarks. Some previous results are updated in the light of these new…
In this talk, I address some recent developments in chiral perturbation theory at unphysical and physical quark masses.
The status of some of the recently discovered heavy hadrons is presented.
