Feebly Interacting Particles: FIPs 2022 workshop report
/ Antel, C. (Geneva U.) ; Battaglieri, M. (INFN, Genoa) ; Beacham, J. (Duke U.) ; Boehm, C. (Sydney U.) ; Buchmüller, O. (Imperial Coll., London) ; Calore, F. (Annecy, LAPTH) ; Carenza, P. (Stockholm U., OKC) ; Chauhan, B. (U. Iowa, Iowa City) ; Cladè, P. (Paris, Lab. Kastler Brossel) ; Coloma, P. (Madrid, IFT ; Madrid, Autonoma U.) et al.
Particle physics today faces the challenge of explaining the mystery of dark matter, the origin of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent fine-tuning of the electro-weak scale, and many other aspects of fundamental physics. Perhaps the most striking frontier to emerge in the search for answers involves new physics at mass scales comparable to familiar matter, below the GeV-scale, or even radically below, down to sub-eV scales, and with very feeble interaction strength.

Nuclear moments and isotope shifts of the actinide isotopes Cf249–253 probed by laser spectroscopy
/ Weber, Felix (Mainz U., Inst. Phys.) ; Albrecht-Schönzart, Thomas E (Florida State U.) ; Allehabi, Saleh O (New South Wales U.) ; Berndt, Sebastian (Mainz U., Inst. Phys. ; Mainz U.) ; Block, Michael (Darmstadt, GSI ; Mainz U. ; Helmholtz Inst., Mainz) ; Dorrer, Holger (Mainz U.) ; Düllmann, Christoph E (Darmstadt, GSI ; Mainz U. ; Helmholtz Inst., Mainz) ; Dzuba, Vladimir A (New South Wales U.) ; Ezold, Julie G (Oak Ridge) ; Flambaum, Victor V (New South Wales U.) et al.
We report on high-resolution laser spectroscopy studies on Cf249–253 with spectral linewidths in the order of 100 MHz carried out at the RISIKO mass separator at Mainz University. In total three atomic ground-state transitions were investigated and the hyperfine parameters for the odd-A isotopes and isotope shift for all examined isotopes have been determined from the measured spectra.

Cold atoms in space: community workshop summary and proposed road-map
/ Alonso, Iván (Balearic Islands U.) ; Alpigiani, Cristiano (Washington U., Seattle) ; Altschul, Brett (South Carolina U.) ; Araújo, Henrique (Imperial Coll., London) ; Arduini, Gianluigi (CERN) ; Arlt, Jan (Aarhus U.) ; Badurina, Leonardo (King's Coll. London) ; Balaž, Antun (Belgrade, Inst. Phys.) ; Bandarupally, Satvika (Florence U. ; INFN, Florence) ; Barish, Barry C. (LIGO Lab., Caltech) et al.
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportunities offered by their deployment in space, and the developments needed before cold atoms could be operated in space. The cold atom technologies discussed include atomic clocks, quantum gravimeters and accelerometers, and atom interferometers. [...]

Expanding Nuclear Physics Horizons with the Gamma Factory
/ Budker, Dmitry (Mainz U. ; Helmholtz Inst., Mainz) ; Berengut, Julian C. (New South Wales U. ; Heidelberg, Max Planck Inst.) ; Flambaum, Victor V. (New South Wales U. ; Mainz U. ; Helmholtz Inst., Mainz ; Massey U., NZIAS) ; Gorchtein, Mikhail (Mainz U.) ; Jin, Junlan (USTC, Hefei) ; Karbstein, Felix (Helmholtz Inst., Mainz ; Jena U.) ; Krasny, Mieczyslaw Witold (Paris U., VI-VII ; CERN) ; Litvinov, Yuri A. (Darmstadt, GSI) ; Pálffy, Adriana (Erlangen - Nuremberg U., Theorie III) ; Pascalutsa, Vladimir (Mainz U.) et al.
The Gamma Factory (GF) is an ambitious proposal, currently explored within the CERN Physics Beyond Colliders program, for a source of photons with energies up to $\approx 400\,$MeV and photon fluxes (up to $\approx 10^{17}$ photons per second) exceeding those of the currently available gamma sources by orders of magnitude. The high-energy (secondary) photons are produced via resonant scattering of the primary laser photons by highly relativistic partially-stripped ions circulating in the accelerator. [...]

Atomic physics studies at the Gamma Factory at CERN
/ Budker, Dmitry (Helmholtz Inst., Mainz ; UC, Berkeley) ; Crespo López‐Urrutia, José R. (Heidelberg, Max Planck Inst.) ; Derevianko, Andrei (Nevada U., Reno) ; Flambaum, Victor V. (New South Wales U. ; Helmholtz Inst., Mainz ; Massey U., NZIAS) ; Krasny, Mieczyslaw Witold (Paris U., VI-VII ; CERN) ; Petrenko, Alexey (Novosibirsk, IYF ; CERN) ; Pustelny, Szymon (Jagiellonian U.) ; Surzhykov, Andrey (Braunschweig, Phys. Tech. Bund. ; Braunschweig Tech. U.) ; Yerokhin, Vladimir A. (Braunschweig, Phys. Tech. Bund. ; St. Petersburg Polytechnic Inst.) ; Zolotorev, Max (LBL, Berkeley)
The Gamma Factory initiative proposes to develop novel research tools at CERN by producing, accelerating and storing highly relativistic, partially stripped ion beams in the SPS and LHC storage rings. By exciting the electronic degrees of freedom of the stored ions with lasers, high-energy narrow-band photon beams will be produced by properly collimating the secondary radiation that is peaked in the direction of ions' propagation.

High magnetic fields for fundamental physics
/ Battesti, Rémy (LNCMI, Toulouse) ; Beard, Jerome (LNCMI, Toulouse) ; Böser, Sebastian (Mainz U., Inst. Phys.) ; Bruyant, Nicolas (LNCMI, Toulouse) ; Budker, Dmitry (Mainz U., Inst. Phys. ; Helmholtz Inst., Mainz ; UC, Berkeley ; LBL, Berkeley) ; Crooker, Scott A. (Los Alamos) ; Daw, Edward J. (Sheffield U.) ; Flambaum, Victor V. (Mainz U., Inst. Phys. ; Helmholtz Inst., Mainz ; New South Wales U.) ; Inada, Toshiaki (Tokyo U., ICEPP) ; Irastorza, Igor G. (Zaragoza U.) et al.
Various fundamental-physics experiments such as measurement of the birefringence of the vacuum, searches for ultralight dark matter (e.g., axions), and precision spectroscopy of complex systems (including exotic atoms containing antimatter constituents) are enabled by high-field magnets. We give an overview of current and future experiments and discuss the state-of-the-art DC- and pulsed-magnet technologies and prospects for future developments..
