Mechanisms of $D D ˉ$ pair production in $e^{+} e^{-} \to e^{+} e^{-} D D ˉ$ and $AA \to AA D D ˉ$ reactions and production of exotic charmonia

Antoni Szczurek, Izabela Babiarz, Piotr Lebiedowicz +1

We discuss mechanisms of $D D ˉ$ pair production in $e^{+} e^{-}$ collisions. We consider the $D^{0} D ˉ^{0}$ -continuum mechanism with the $t / u$ -channel $D^{*}$ vector-meson exchang…

Central exclusive production of scalar and pseudoscalar charmonia in the light-front $k_{T}$ -factorization approach

Izabela Babiarz, Roman Pasechnik, Wolfgang Schäfer +1

We study exclusive production of scalar $χ_{c 0} \equiv χ_{c} (0^{++})$ and pseudoscalar $η_{c}$ charmonia states in proton-proton collisions at the LHC energies. The amplitudes for $gg \…

Hadroproduction of scalar $P$ -wave quarkonia in the light-front $k_{T}$ -factorization approach

Izabela Babiarz, Roman Pasechnik, Wolfgang Schäfer +1

In this work, we present a thorough analysis of scalar $P$ -wave $χ_{Q 0}$ , $Q = c, b$ quarkonia electromagnetic form factors for the $γ^{*} γ^{*} \to χ_{Q 0}$ couplings, as well as their ha…

Exclusive production of $ϕ$ meson in the $γ^{*} p \to ϕ p$ reaction at large photon virtualities within $k_{T}$ -factorization approach

A. D. Bolognino, A. Szczurek, W. Schäfer

We apply the $k_{T}$ -factorization approach to the production of $ϕ$ meson in deep-inelastic scattering. The helicity-conserving $γ^{*} (T, L) \to ϕ$ impact factor is calculated for long…

The $γ^{} γ^{} \to η_{c} (1 S, 2 S)$ transition form factors for spacelike photons

Izabela Babiarz, Victor P. Goncalves, Roman Pasechnik +2

We derive the light-front wave function (LFWF) representation of the $γ^{*} γ^{*} \to η_{c} (1 S), η_{c} (2 S)$ transition form factor $F (Q_{1}^{2}, Q_{2}^{2})$ for two virtual photons in the initial…

Rapidity gap survival factors caused by remnant fragmentation for $W^{+} W^{-}$ pair production via $γ^{} γ^{} \to W^{+} W^{-}$ subprocess with photon transverse momenta

Laurent Forthomme, Marta Łuszczak, Wolfgang Schäfer +1

We calculate the cross section for $pp \to W^{+} W^{-}$ in the recently developed $k_{T}$ -factorisation approach, including transverse momenta of the virtual photons. We focus o…
