The last two decades have witnessed the discovery of a myriad of new and unexpected
hadrons. The future holds more surprises for us, thanks to new-generation experiments …

This manual describes the Pythia event generator, the most recent version of an evolving
physics tool used to answer fundamental questions in particle physics. The program is most …

Structure in the di-J/ψ mass spectrum observed by the LHCb experiment around 6.9 and 7.2
GeV is interpreted in terms of JPC= 0++ and 2++ resonances between acc diquark and ac¯ …

For several decades, the σ/f 0 (500) and κ/K 0∗(700) resonances have been subject to long-
standing debate. Both their existence and properties were controversial until very recently. In …

We analyze the spectrum of two-and three-pion states of maximal isospin obtained recently
for isosymmetric QCD with pion mass M≈ 200 MeV in Hörz and Hanlon,[Phys. Rev. Lett …

Urgent theoretical progress is needed in order to provide an estimate in the Standard Model
of the recent measurement by LHCb of direct CP violation in charm-meson two-body decays …

We show that final state interactions (FSI) within a CPT invariant two-channel framework can
enhance the charge-parity (CP) violation difference between D 0→ π-π+ and D 0→ K-K+ …

In a recent article we presented a model for hadronic rescattering, and some results were
shown for pp pp collisions at LHC energies. In order to extend the studies to p A p A and AA …

The exclusive production of pion pairs in the process pp→ pp π+ π-has been measured at
s= 7 TeV with the ATLAS detector at the LHC, using 80 μ b-1 of low-luminosity data. The …

We perform a systematic analysis of the\(J/\psi\rightarrow\gamma\pi^ 0\pi^ 0\)
and\(\rightarrow\gamma K_S^ 0 K_S^ 0\) partial waves measured by BESIII. We use a large …
