Two photon decay width of the fully charmed tetraquarks: revisiting prospects for ultraperipheral collisions

Longjie Chen, Wolfgang Schäfer, Antoni Szczurek

We discuss the role of fully heavy tetraquarks in ultraperipheral collisions and . Two-photon couplings to scalar and tensor tetraquarks are…

Probing GPDs in exclusive electroproduction of dijets

Trambak Jyoti Chall, Marta Łuszczak, Wolfgang Schäfer +1

We summarize the formalism for calculating the exclusive dijet production in in collinear QCD factorization, using generalized parton distributions as the…

Production of pairs in diffractive photon-proton and in proton-proton collisions revisited, in particular concerning the Drell-Söding contribution

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We discuss the exclusive photoproduction of pairs in photon-proton and in proton-proton collisions at high energies. The , , , and non-reson…

Central exclusive production of and mesons in diffractive proton-proton collisions at the LHC and the nature of the pomeron

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

Central exclusive production (CEP) of and mesons in proton-proton collisions at high-energies is discussed. At the LHC the main mechanism for the production of these mes…
