Production of $I ¨ ^{+} I ¨ ^{-}$ pairs in diffractive photon-proton and in proton-proton collisions revisited, in particular concerning the Drell-SÃ¶ding contribution

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We discuss the exclusive photoproduction of $I ¨ ^{+} I ¨ ^{-}$ pairs in photon-proton and in proton-proton collisions at high energies. The $I ¨ ^{0}$ , $I ¨ $ , $f_{2} (1270)$ , and non-reson…

Exclusive $D D ˉ$ pair production with low invariant mass in ultraperipheral Pb-Pb collisions at the LHC

Piotr Lebiedowicz, Antoni Szczurek

We present predictions for the ultraperipheral heavy-ion reaction $Pb Pb \to Pb Pb D D ˉ$ , where $D$ refers to either $D^{0}$ or $D^{+}$ , limiting to low in…

Competition of $I ¨ _{c} (2 P)$ quarkonia and continuum in $e^{+} e^{-} \to e^{+} e^{-} D D ˉ$

Izabela Babiarz, Piotr Lebiedowicz, Wolfgang SchÃ¤fer +1

We discuss the production of $D D ˉ$ pairs in $e^{+} e^{-}$ collisions, where $D$ refers to either $D^{0}$ or $D^{+}$ . The continuum mechanism with the $t / u$ -channel vector-meson $D^{*}$ …

Central exclusive production of $I^\cdot$ and $I^\cdot^{'}$ 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 $I^\cdot$ and $I^\cdot^{'}$ mesons in proton-proton collisions at high-energies is discussed. At the LHC the main mechanism for the production of these mes…

Central exclusive production of $I^\cdot$ and $I^\cdot^{'}$ 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 $I^\cdot$ and $I^\cdot^{'} (958)$ mesons in diffractive proton-proton collisions at high energies. The amplitudes, including pomer…

Exclusive $I^\cdot$ production in proton-proton collisions at energies available at the GSI Facility for Antiproton and Ion Research

Piotr Lebiedowicz

The cross sections for the $pp \to pp I^\cdot$ reaction are evaluated at energies relevant for the HADES, PANDA, and SIS100 experiments at GSI-FAIR. Consideration includes the $I^\cdot$ -br…
