Lhc Hunting the Odderon: is it Really Caught? / Petrov, Vladimir A. (Serpukhov, IHEP)
We give a short survey of recent LHC experiments and related theory topics concerning the Odderon problem..

Double-crystal measurements at the CERN SPS / Scandale, W. (CERN ; Imperial Coll., London ; INFN, Rome) ; Arduini, G. (CERN) ; Cerutti, F. (CERN) ; D'Andrea, M. (CERN ; Padua U.) ; Esposito, L.S.

(CERN ; IJCLab, Orsay ; Taras Shevchenko U.) et al.
The UA9 setup, installed in the Super Proton Synchrotron (SPS) at CERN, was exploited for a proof of principle of the double-crystal scenario, proposed to measure the electric and the magnetic moments of short-lived baryons in a high-energy hadron collider, such as the Large Hadron Collider (LHC). Linear and angular actuators were used to position the crystals and establish the required beam configuration. [...]

Odderon observation: explanations and answers to questions/objections regarding the PRL publication / Österberg, Kenneth (Helsinki Inst. of Phys.)
The odderon observation recently published by the D0 and TOTEM collaborations has been widely accepted by a majority of the particle physics community and its importance recognized through dedicated physics seminars in the world major labs and physics institute. [...]

Exotic meson $\pi_1(1600)$ with $J^{PC} = 1^{-+}$ and its decay into $\rho(770)\pi$ / COMPASS Collaboration
We study the spin-exotic $J^{PC} = 1^{-+}$ amplitude in single-diffractive dissociation of 190 GeV$/c$ pions into $\pi^-\pi^-\pi^+$ using a hydrogen target and confirm the $\pi_1(1600) \to \rho(770) \pi$ amplitude, which interferes with a nonresonant $1^{-+}$ amplitude. We demonstrate that conflicting conclusions from previous studies on these amplitudes can be attributed to different analysis models and different treatment of the dependence of the amplitudes on the squared four-momentum transfer and we thus reconcile their experimental findings.

Track reconstruction and matching between emulsion and silicon pixel detectors for the SHiP-charm experiment / SHiP Collaboration
In July 2018 an optimization run for the proposed charm cross section measurement for SHiP was performed at the CERN SPS. A heavy, moving target instrumented with nuclear emulsion films followed by a silicon pixel tracker was installed in front of the Goliath magnet at the H4 proton beamline. [...]

Integrating LHCb workflows on HPC resources: status and strategies / Stagni, Federico (CERN) ; Valassi, Andrea (CERN) ; Romanovskiy, Vladimir (Kurchatov Inst., Moscow)
High Performance Computing (HPC) supercomputers are expected to play an increasingly important role in HEP computing in the coming years. While HPC resources are not necessarily the optimal fit for HEP workflows, computing time at HPC centers on an opportunistic basis has already been available to the LHC experiments for some time, and it is also possible that part of the pledged computing resources will be offered as CPU time allocations at HPC centers in the future.

Odderon and proton substructure from a model-independent Lévy imaging of elastic $pp$ and $p\bar{p}$ collisions / Csörgő, T. (Wigner RCP, Budapest ; Karoly Robert U. Coll. ; CERN) ; Pasechnik, R. (Lund U., Dept. Theor. Phys. ; Prague, Inst. Phys.) ; Ster, A. (Wigner RCP, Budapest)
We describe a new and model-independent L\'evy imaging method of quality fits to the published datasets and reconstruct the amplitude of high-energy $pp$ and $p\bar p$ elastic scattering processes. This method allows us to determine the excitation function of the shadow profile $P(b)$, the elastic slope $B(t)$ and the nuclear phase $\phi(t)$ functions of $pp$ and $p\bar p$ collisions directly from the data.

Searching for the odderon in $pp \to pp K^{+}K^{-}$ and $pp \to pp \mu^{+}\mu^{-}$ reactions in the $\phi(1020)$ resonance region at the LHC / Lebiedowicz, Piotr (Cracow, INP) ; Nachtmann, Otto (U. Heidelberg, ITP ; Rzeszow U.) ; Szczurek, Antoni (Cracow, INP)
We explore the possibility of observing odderon exchange in the $pp \to pp K^{+}K^{-}$ and $pp \to pp \mu^{+}\mu^{-}$ reactions at the LHC. We consider the central exclusive production (CEP) of the $\phi(1020)$ resonance decaying into $K^{+} K^{-}$ and $\mu^{+}\mu^{-}$. [...]

Searching for Odderon in Central Exclusive Processes at the LHC / Lebiedowicz, Piotr (Cracow, INP)
There seem to be recently an evidence for $C = -1$ odderon exchange in proton-proton elastic scattering at high energies. Here we discuss three different central-exclusive-production processes $pp \to pp (\phi \to K^{+}K^{-})$, $pp \to pp (\phi \to \mu^{+}\mu^{-})$, and $pp \to pp \phi \phi \to pp K^{+}K^{-}K^{+}K^{-}$, as a possible source of information for soft odderon exchange.
