RF-Separated Beam Project for the M2 Beam Line at CERN / Gerbershagen, Alexander (CERN) ; Andrieux, Vincent (Univ. Illinois at Urbana Champaign (US)) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Denisov, Oleg (Universita e INFN Torino (IT)) ; Friedrich, Jan (Technische Universitaet Muenchen (DE)) ; Gatignon, Lau (Lancaster University (GB)) ; Gerigk, Frank (CERN) ; Guskov, Alexey (Joint Institute for Nuclear Research (RU)) ; Ketzer, Bernhard (University of Bonn (DE)) et al.
Within the framework of the Physics Beyond Colliders initiative at CERN, discussions are underway on the feasibility of producing radio-frequency (RF) separated beams for Phase-2 of the AMBER experiment at the M2 beam line in the North experimental area of the CERN SPS. The technique of RF separation is applied to enrich the content of a certain particle type within a beam consisting of different species at the same momentum [...]

The Forward Physics Facility at the High-Luminosity LHC / Boyd, Jamie (CERN) ; Feng, Jonathan Lee (University of California Irvine (US)) ; Rojo Chacon, Juan (Nikhef National institute for subatomic physics (NL)) ; Kling, Felix (DESY) ; Reno, Mary (University of Iowa) ; Soldin, Dennis (University of Delaware)
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located several hundred meters from the ATLAS interaction point and shielded by concrete and rock, will host a suite of experiments to probe Standard Model (SM) processes and search for physics beyond the Standard Model (BSM) [...]

The Forward Physics Facility: Sites, experiments, and physics potential / Anchordoqui, Luis A. (Lehman Coll.) ; Ariga, Akitaka (Bern U., LHEP ; Chiba U.) ; Ariga, Tomoko (Kyushu U., Fukuoka (main)) ; Bai, Weidong (Zhongshan U.) ; Balazs, Kincso (CERN) ; Batell, Brian (Pittsburgh U.) ; Boyd, Jamie (CERN) ; Bramante, Joseph (Queen's U., Kingston) ; Campanelli, Mario (University Coll. London) ; Carmona, Adrian (CAFPE, Granada) et al.
The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider during the High Luminosity era. Located along the beam collision axis and shielded from the interaction point by at least 100 m of concrete and rock, the FPF will house experiments that will detect particles outside the acceptance of all existing LHC experiments and will observe rare and exotic processes in an extremely low-background environment.

Considerations for a RF separated K+ beam for NA62 / Appleby, Robert Barrie (University of Manchester (GB)) ; Bernhard, Johannes (CERN) ; Dainton, John Bourke (Lancaster University (GB)) ; Burt, Graeme Campbell (Lancaster University (GB)) ; Gatignon, Lau (Lancaster University (GB)) ; Goudzovski, Evgueni (University of Birmingham (GB)) ; Jones, Rhodri (CERN) ; Lazzeroni, Cristina (University of Birmingham (GB)) ; Romano, Angela (University of Birmingham (GB)) ; Giuseppe, Ruggiero (Dipartimento di Fisica e Astronomia) et al.
In this document we assess the potential of RF separation to increase the kaon content of the high-intensity secondary beam to the NA62 experiment in the CERN North Area. The present mixed beam provides a nominal kaon flux of 45 MHz out of a total beam intensity of about 750 MHz. [...]

Physics opportunities for a fixed-target programme in the ALICE experiment / Galluccio, Francesca (Universita e sezione INFN di Napoli (IT)) ; Hadjidakis, Cynthia (Centre National de la Recherche Scientifique (FR)) ; Kurepin, Alexander (Institute for Nuclear Research, Moscow) ; Massacrier, Laure (Centre National de la Recherche Scientifique (FR)) ; Porteboeuf, S (Centre national de la recherche scientifique (FR)) ; Pressard, Kevin (Centre national de la recherche scientifique (FR)) ; Scandale, Walter (CERN) ; Topilskaya, Natalia (Institute for Nuclear Research, Moscow) ; Trzeciak, Barbara (Utrecht University) ; Uras, Antonio (Centre national de la recherche scientifique (FR)) et al.
A fixed-target programme in the ALICE experiment using the LHC proton and lead beams offers many physics opportunities related to the parton content of the nucleon and nucleus at high-$x$, the nucleon spin and the Quark-Gluon Plasma. We investigate two solutions that would allow ALICE to run in a fixed-target mode: the internal solid target coupled to a bent crystal and the internal gas target. [...]
