## PHOTON 2019  –  International Conference on the Structure and the Interactions of the Photon. Satellite Workshop: Photon Physics and Simulation at Hadron Colliders.

This conference is part of the series initiated in 1973 in Paris, as an International Colloquium on Photon-Photon Collisions at Electron-Positron Storage Rings. The latest Photon conferences took place in CERN-Geneva (2017), Novosibirsk (2015), Paris (2013), Spa (2011), Hamburg (2009), Paris (2007), Warsaw (2005), Frascati (2003), Ascona (2001), Freiburg (2000), Ambleside (1999), and Egmond aan Zee (1997). The scientific program will include topics related to photon-photon and photon-hadron collisions as well as final-state photon production at current and future colliders. In addition, high-energy astrophysics gamma-rays, and photon-related searches of new physics (axions, dark/hidden photons, …) will also be discussed. The conference format consists of talks in plenary sessions only. The LOC offers a number of young researcher grants to attend the conference. Interested participants are invited to send an e-mail to photon19_loc@lists.lnf.infn.it with their motivated request for support. The 2019 Edition of the Colloquium will be hosted in the first established laboratory of the Italian National Institute of Nuclear Physics (awarded also as EPS historical site) the place where in 1959, exactly 60 years ago, the first Italian Electro-Syncroton started its operations. Here, the year after, the first matter-antimatter collider (AdA) ever built saw the light.

## New Probes of Ultra-Low-Mass Dark Matter and Dark Sectors

I present a brief overview of some novel detection strategies for ultra-low-mass bosonic dark matter that forms a coherently oscillating classical field. Possible effects of such dark matter fields include time-varying spin-precession effects and time-varying fundamental constants. These effects can be sought with various low-energy atomic and astrophysical probes, including magnetic resonance techniques, spectroscopy measurements, microwave/optical cavities (maser/laser interferometers), fifth-force experiments, and Big Bang nucleosynthesis. Further possible effects of dark bosons include the mediation of anomalous new forces that can be sought with electric dipole moment experiments, parity non-conservation experiments and (antimatter) spectroscopy measurements. Existing and new experimental and observational data have allowed us and other groups to improve on previous observational bounds on dark matter and dark boson interactions by many orders of magnitude.

## Very high field magnets for next hadron colliders: new technologies and opportunities

To decisively upgrade the luminosity of the LHC, and increase its Physics reach, the High Luminosity LHC project is opening a new territory, developing a broad range of new technologies: accelerator magnets in the 12 tesla range based on advanced Nb3Sn technology, long superconducting links rated for 100 kA with novel MgB2 superconductors, new type of SRF cavities, etc…. The talk will discuss the status of these new technologies for HL-LHC and especially the high field magnets, now at the verge of entering into production, as well as the studies under way for the post-LHC Hadron Collider. In particular, for the FCC stronger Nb3Sn magnets, for 16 T, are under design and the first R&D on HTS (High Temperature Superconductors) accelerator magnets has started. HTS magnet results are promising to open the 20 T range, which would bring the 100 km FCC even beyond the 100 TeV threshold.

## Low-energy strangeness studies at DAFNE and J-PARC

The aim of the "Low-energy strangeness studies ad DAFNE and J-PARC" workshop is to give an outline of the major issues in the low energy strangeness nuclear physics sector and to discuss still open problems to be addressed in the near future.    The low energy strangeness QCD represents one of the most interesting sectors in physics,the existence of broad hyperon resonances just below the Kbar-N threshold, like the debated Lambda* state, makes the  Kbar-N  interaction a complicated non-perturbative and multi-channel problem which puzzled theoreticians and experimentalists for decades.   The accurate investigation of the Kbar-N and Hyperons-N interaction above, below and at the threshold deeply impacts many sectors of physics ranging from nuclear physics to astrophysics.    The workshop is organized in the framework of the StrangeMatter Italy-Japan project supported by the Ministero degli Affari Esteri e della Collaborazione Internazionale (MAECI) and is sponsored by the Istituto Nazionale di Fisica Nucleare and by the CENTRO FERMI – Museo Storico della Fisica e Centro Studi e Ricerche Enrico Fermi. Local Organizing Committee:   Catalina Curceanu Raffaele Del Grande Kristian Piscicchia Alessandro Scordo Diana Laura Sirghi Magdalena Skurzok Alessandra Tamborrino Orsini

## Could synchrotron light sources benefit from the CERN experience with beams split in horizontal phase space?

This talk reviews the recent activities carried out at CERN in terms of transverse beam splitting with proton beams. Thanks to intense experimental and theoretical activities, the recently-proposed approach of splitting beams in the horizontal phase space using stable islands moved out of the test stage to beoame a mature technique of beam manipulation to perform multi-turn extraction. It is therefore timely to address the question whether stable islands can be applied to other branches of accelerator physics, in view of bringing new means of improving ring’s performance. This is the case of synchrotron light machines, where the use of stable islands could lead to new developments that will be presented and discussed.

## Spin-azimuthal asymmetries in SIDIS: from JLab12 to EIC

The study of the 3D nucleon structure by probing the transverse momentum dependent (TMD) distributions of partons in Semi-Inclusive DIS is widely accepted as one of the main goals of the future Electron Ion Collider (EIC). Much wider kinematical coverage, and in particular higher $P_T$ and $Q^2$, would allow validating and extending studies of evolution properties of TMDs planned at JLab12, and access the sea and gluon distributions. The EIC would allow much better separation of current fragmentation and target fragmentation regions than JLab12, and due to high polarization of electrons and protons is a natural choice for measurements of different spin dependent observables in a full range of accessible kinematics. EIC provides also a unique possibility for detection of hadrons produced in the target fragmentation region, providing a new avenue for studies of the non-perturbative structure of the nucleon in correlations of hadrons produced in DIS regime. In this talk, we present an overview of the current status and some future measurements of the orbital structure of nucleons and nuclei at JLab and EIC.
