Central production of $ρ^{0}$ in $pp$ collisions with single proton diffractive dissociation at the LHC

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We consider the $pp \to pp ρ^{0} π^{0}$ and $pp \to p n ρ^{0} π^{+}$ processes at LHC energies. Our description is based on the nonperturbative framework of tensor pomeron and tenso…

LHC Forward Physics

K. Akiba, M. Akbiyik, M. Albrow +184

The goal of this report is to give a comprehensive overview of the rich field of forward physics, with a special attention to the topics that can be studied at the LHC. The report…

Exclusive production of two and four pions in proton-proton scattering

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We consider exclusive $pp \to pp π^{+} π^{-}$ and $pp \to pp π^{+} π^{-} π^{+} π^{-}$ reactions at high energies. The calculation is based on a tensor pomeron model and the amplitud…

Interpreting the 750 GeV diphoton signal as technipion

Piotr Lebiedowicz, Marta Luszczak, Roman Pasechnik +1

We discuss whether the enhancement in the diphoton final state at $M_{γ γ}$ = 750 GeV, observed recently by the ATLAS and CMS Collaborations could be a neutral pseudoscalar technipi…

Exclusive diffractive production of $π^{+} π^{-}$ pairs within tensor pomeron approach

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We discuss exclusive central diffractive production of $π^{+} π^{-}$ in proton-(anti)proton collisions at high energies. Based on a tensor pomeron model we present results of the p…

Light-by-light scattering in UPC at the LHC

Mariola Klusek-Gawenda, Piotr Lebiedowicz, Antoni Szczurek

We discuss diphoton semi(exclusive) production in ultraperipheral $P b P b$ collisions at energy of $s_{N N} =$ 5.5 TeV (LHC). The nuclear calculations are based on equivalent ph…

Helicity in Proton-Proton Elastic Scattering and the Spin Structure of the Pomeron

Carlo Ewerz, Piotr Lebiedowicz, Otto Nachtmann +1

We discuss different models for the spin structure of the nonperturbative pomeron: scalar, vector, and rank-2 symmetric tensor. The ratio of single-helicity-flip to helicity-conser…

Exclusive diffractive production of $π^{+} π^{-} π^{+} π^{-}$ via the intermediate $σ σ$ and $ρρ$ states in proton-proton collisions within tensor pomeron approach

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We present first predictions of the cross sections and differential distributions for the central exclusive reaction $pp \to pp π^{+} π^{-} π^{+} π^{-}$ being studied at RHIC and L…

Light-by-light scattering in ultraperipheral heavy-ion collisions at the LHC

Antoni Szczurek, Mariola Klusek-Gawenda, Piotr Lebiedowicz

We present cross sections for diphoton production in (semi)exclusive $P b P b$ collisions, relevant for the LHC. The calculation is based on equivalent photon approximation in the imp…

Can the diphoton enhancement at 750 GeV be due to a neutral technipion?

Piotr Lebiedowicz, Marta Luszczak, Roman Pasechnik +1

We discuss a scenario in which the diphoton enhancement at $M_{γ γ}$ = 750 GeV, observed by the ATLAS and CMS Collaborations, is a neutral technipion $π ~^{0}$ . We consider two di…

Central exclusive diffractive production of $π^{+} π^{-}$ continuum, scalar and tensor resonances in $pp$ and $p p ˉ$ scattering within tensor pomeron approach

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

We consider central exclusive diffractive dipion production in the reactions $pp \to pp π^{+} π^{-}$ and $p p ˉ \to p p ˉ π^{+} π^{-}$ at high energies. We include the dipion…
