Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

Multiquark resonances are undoubtedly experimentally observed. The number of states and
the amount of details on their properties have been growing over the years. It is very recent …

Conventional, hadronic matter consists of baryons and mesons made of three quarks and a
quark–antiquark pair, respectively,. Here, we report the observation of a hadronic state …

Quantum chromodynamics, the theory of the strong force, describes interactions of coloured
quarks and gluons and the formation of hadronic matter. Conventional hadronic matter …

Observations of exotic structures in the J/ψ p channel, which we refer to as charmonium-
pentaquark states, in Λ b 0→ J/ψ Kp decays are presented. The data sample corresponds to …

The Pythia program can be used to generate high-energy-physicsevents', ie sets of outgoing
particles produced in the interactions between two incoming particles. The objective is to …

Why do we see certain types of strongly interacting elementary particles and not others?
This question was posed more than 50 years ago in the context of the quark model. M. Gell …

We describe in detail how the different components of a multiphase transport (ampt) model
that uses the heavy ion jet interaction generator (hijing) for generating the initial conditions …

Heavy-light diquarks can be the building blocks of a rich spectrum of states which can
accommodate some of the newly observed charmoniumlike resonances not fitting a pure …

Soft multiparticle production is a dominant feature of most events in high energy hadronic
collisions. Since soft processes have no large momentum transfer, perturbative QCD …
