Exclusive production of $π^{+} π^{-}$ pairs in diffractive $γ p$ and in $pp$ collisions within the tensor-pomeron approach

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We discuss exclusive production of $π^{+} π^{-}$ pairs in diffractive $γ p$ and in $pp$ collisions at high energies, considering resonant ( $ρ (770)$ , $ω$ , $f_{2} (1270)$ ) and non-resonant (…

Central exclusive production of $η$ and $η^{'}$ mesons in diffractive proton-proton collisions at the LHC

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We discuss central exclusive production (CEP) of $η$ and $η^{'} (958)$ mesons in high-energy proton-proton collisions using the tensor-pomeron approach, incorporating absorption effect…

Addendum: Production of $π^{+} π^{-}$ 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 update our analyses concerning the non-resonant (Drell-Söding) contribution to the reaction $γ^{(*)} p \to π^{+} π^{-} p$ , now including general vertex functions for the couplin…

Production of $π^{+} π^{-}$ 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 $π^{+} π^{-}$ pairs in photon-proton and in proton-proton collisions at high energies. The $ρ^{0}$ , $ω$ , $f_{2} (1270)$ , and non-resonant…

Central exclusive production of $η$ and $η^{'}$ mesons in diffractive proton-proton collisions at the LHC within the tensor-pomeron approach

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We present a study of the central exclusive production (CEP) of $η$ and $η^{'} (958)$ mesons in diffractive proton-proton collisions at high energies. The amplitudes, including pomeron…

Exclusive Bremsstrahlung of One and Two Photons in Proton-Proton Collisions

Piotr Lebiedowicz, Antoni Szczurek, Otto Nachtmann

We discuss the diffractive bremsstrahlung of a single photon in the $pp \to pp γ$ reaction at LHC energies and at forward photon rapidities. We compare the results for our standard…
