Low-energy QCD
Oral presentation
We perform Dalitz plot analyses of $J/\psi$ three-body hadronic decays to $\pi^+ \pi^-\pi^0$, $K^+ K^-\pi^0$ and $K^0_S K^{\pm} \pi^{\mp}$ using the isobar and Veneziano models. The $J/\psi$ is produced through the Inital-State-Radiation process.
We also perform Dalitz plot analyses of $\eta_c$ three-body hadronic decays to $K^+ K^-\pi^0$ and $K^0_S K^{\pm} \pi^{\mp}$, where the $\eta_c$ is...

Hadron physics at LHC
Oral presentation
Recent model-independent measurements of the absolute branching ratio of the normalisation mode Lambda_c -> p^+ K^- pi^+ by the Belle1 and BES32 collaborations have significantly increased the precision of previously measured decay channels. BES3 also independently updated the value for the Sigma^+ pi^- pi^+ mode, however the branching fraction into the Sigma^0 pi^0 pi^+ decay channel has not...

Oral presentation
The Belle II experiment, being constructed at the KEK laboratory in Japan, is a substantial upgrade of both the Belle detector and the KEKB accelerator. It aims at collecting 50 times more data than existing B-Factory samples beginning in 2019. Belle II is uniquely capable of studying the so-called "XYZ" particles: heavy exotic hadrons consisting of more than three quarks.
First discovered...

Hadron physics at LHC
Oral presentation
We introduce the use of the Weibull distribution as a simple parametrization of charged particle multiplicities in hadron-hadron collisions at all available energies, ranging from ISR energies to the most recent LHC energies. In statistics, the Weibull distribution has wide applicability in natural processes that involve fragmentation processes. This provides a natural connection to the...

Hadron physics at LHC
Oral presentation
The Large Hadron Collider (LHC) has delivered at the end of 2015 Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV. This data sample from the so-called LHC Run 2, complements the Run 1 datasets of Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV. These datasets allow for a systematic study of the light (anti-)(hyper-)nuclei production in ultra relativistic heavy ion collisions. Thanks to...

Hadron physics at LHC
Oral presentation
We report measurements of the differential cross sections and polarizations of B hadron and quarkonium states. These are important tools to investigate heavy-quark production mechanisms in QCD. The dependences on transverse momentum, rapidity, and particle multiplicity are investigated. Comparisons with theory expectations and among different collision energies are provided.

Oral presentation
The large sample of high quality data taken in pp collisions at $\sqrt{s} = 7$ TeV and 13 TeV and in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV at the LHC with the ALICE detector allows for a systematic study of the light (anti-)nuclei production in these collision systems.
The excellent performance of the Inner Tracking System, the Time Projection Chamber and the Time-Of-Flight...

Hadron physics at LHC
Oral presentation
We present precise measurements of decay properties of hadrons containing a b quark performed on the data collected by the CMS experiment at LHC. The lifetime is among the fundamental properties of particles and in heavy hadrons it is one of the important observables that allows to test the theoretical tools describing their physics. Some of the reported measurements are at the precision level...

Hadron physics at LHC
Oral presentation
The measurement of the mass-to-charge ratio difference between nuclei and anti-nuclei probes the possibility of subtle differences between the way protons and neutrons bind together in nuclei compared with how their respective anti-particles form anti-nuclei. Such a study provides a quantitative verification of the matter/anti-matter symmetry in the context of the nuclear forces, a remnant of...

Hadron physics at LHC
Oral presentation
The high energy densities reached at LHC lead to the production of a significant amount of light hypernuclei as well as (anti-)nuclei which are consequently observed in several collision systems, namely from proton-proton (pp), to proton-lead (p-Pb) up to lead-lead (Pb-Pb) collisions. Several potentially existing exotic QCD bound states, such as the H- dibaryon, could be produced and they...
