The Forward Physics Facility at the High-Luminosity LHC
/ Feng, Jonathan L. (UC, Irvine) ; Kling, Felix (DESY) ; Reno, Mary Hall (Iowa U.) ; Rojo, Juan (NIKHEF, Amsterdam ; Vrije U., Amsterdam) ; Soldin, Dennis (Delaware U.) ; Anchordoqui, Luis A. (Lehman Coll.) ; Boyd, Jamie (CERN) ; Ismail, Ahmed (Oklahoma State U.) ; Harland-Lang, Lucian (Oxford U. ; Oxford U., Theor. Phys.) ; Kelly, Kevin J. (CERN) et al.
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) [...]

New Physics Searches at Kaon and Hyperon Factories

(Los Alamos) ; Bansal, Saurabh (Cincinnati U.) ; Bauer, Martin (Durham U., ICC) ; Brod, Joachim (Cincinnati U.) ; Chobanova, Veronika (Santiago de Compostela U., IGFAE) et al.
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths and the availability of very large datasets. [...]

Feebly-interacting particles: FIPs 2020 workshop report
/ Agrawal, Prateek (Oxford U., Theor. Phys.) ; Bauer, Martin (Durham U., IPPP) ; Beacham, James (Duke U.) ; Berlin, Asher (New York U., CCPP ; New York U.) ; Boyarsky, Alexey (Leiden U.) ; Cebrian, Susana (Zaragoza U.) ; Cid-Vidal, Xabier (Santiago de Compostela U.) ; d'Enterria, David (CERN) ; De Roeck, Albert (CERN) ; Drewes, Marco (Louvain U., CP3) et al.
With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader particle and astrophysics community for exploring the physics of light and feebly-interacting particles as a paradigm complementary to a New Physics sector at the TeV scale and beyond. FIPs 2020 has been the first workshop fully dedicated to the physics of feebly-interacting particles and was held virtually from 31 August to 4 September 2020. [...]

Flavor probes of axion-like particles
/ Bauer, Martin (Durham U., IPPP) ; Neubert, Matthias (Mainz U., Inst. Phys. ; U. Mainz, PRISMA ; Cornell U., LEPP) ; Renner, Sophie (SISSA, Trieste ; INFN, Trieste ; CERN) ; Schnubel, Marvin (Mainz U., Inst. Phys. ; U. Mainz, PRISMA) ; Thamm, Andrea (Melbourne U.)
Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-energy extensions of the Standard Model (SM). We investigate the phenomenology of an ALP with flavor-changing couplings, and present a comprehensive analysis of quark and lepton flavor-changing observables within a general ALP effective field theory.

Axionlike Particles, Lepton-Flavor Violation, and a New Explanation of $a_\mu$ and $a_e$

Axion-like particles (ALPs) with lepton-flavor violating couplings can be probed in exotic muon and tau decays. The sensitivity of different experiments depends strongly on the ALP mass and its couplings to leptons and photons. [...]

LHC Dark Matter Working Group: Next-generation spin-0 dark matter models
/ LHC Dark Matter Working Group Collaboration
Dark matter (DM) simplified models are by now commonly used by the ATLAS and CMS Collaborations to interpret searches for missing transverse energy ($E_T^\mathrm{miss}$). The coherent use of these models sharpened the LHC DM search program, especially in the presentation of its results and their comparison to DM direct-detection (DD) and indirect-detection (ID) experiments.

Axion-Like Particles at Future Colliders
/ Bauer, Martin (Heidelberg U.) ; Heiles, Mathias (Mainz U., Inst. Phys. ; U. Mainz, PRISMA) ; Neubert, Matthias (Mainz U., Inst. Phys. ; U. Mainz, PRISMA ; Cornell U., LEPP) ; Thamm, Andrea (CERN)
Axion-like particles (ALPs) are pseudo Nambu-Goldstone bosons of spontaneously broken global symmetries in high-energy extensions of the Standard Model (SM). This makes them a prime target for future experiments aiming to discover new physics which addresses some of the open questions of the SM. [...]

Long-Lived Particles at the Energy Frontier: The MATHUSLA Physics Case
/ Curtin, David (Toronto U.) ; Drewes, Marco (Louvain U., CP3) ; McCullough, Matthew (CERN) ; Meade, Patrick (YITP, Stony Brook) ; Mohapatra, Rabindra N. (Maryland U.) ; Shelton, Jessie (Illinois U., Urbana) ; Shuve, Brian (Harvey Mudd Coll. ; SLAC) ; Accomando, Elena (Southampton U.) ; Alpigiani, Cristiano (Washington U., Seattle) ; Antusch, Stefan (Basel U.) et al.
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of a wide range of theories that address unsolved fundamental mysteries such as naturalness, dark matter, baryogenesis and neutrino masses, and represent a natural and generic possibility for physics beyond the SM (BSM).
