Prospects for quarkonium-production studies accessible during the upcoming high-
luminosity phases of the CERN Large Hadron Collider operation after 2021 are reviewed …

A bstract Cross sections for the coherent photoproduction of ρ 0 vector mesons in ultra-
peripheral Pb-Pb collisions at\(\sqrt {{\mathrm {s}} _ {\mathrm {NN}}}\)= 5. 02 TeV are …

A bstract We report on the measurement of the Central Exclusive Production of charged
particle pairs h+ h−(h= π, K, p) with the STAR detector at RHIC in proton-proton collisions …

We present a study of the central exclusive π+ π-production via the photoproduction
mechanism in nucleon-nucleon collisions. The photon-pomeron/reggeon and …

A bstract We consider the reaction γp→ π+ π− p at high energies. Our description includes
dipion production via the resonances ρ, ω, ρ′ and f 2, and via non-resonant mechanisms …

It is long known that interference effects play an important role in understanding the shape of
the π+ π-spectrum of resonances near the threshold. In this manuscript, we investigate the …

Abstract Exclusive photoproduction of ρ^ 0 (770) ρ 0 (770) mesons is studied using the H1
detector at the ep collider HERA. A sample of about 900,000 events is used to measure …

We discuss γ γ→ π π reactions, starting from the two-pion threshold up to about s γ γ= 6
GeV. Several reaction mechanisms are identified. We include the dipion continuum owing to …

K+ K-pairs may be produced in photonuclear collisions, either from the decays of
photoproduced ϕ (1020) mesons or directly as nonresonant K+ K-pairs. Measurements of …

A first measurement is presented of exclusive photoproduction of ρ^ 0 ρ 0 mesons
associated with leading neutrons at HERA. The data were taken with the H1 detector in the …
