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. [...]

Observation of Spin Flips with a Single Trapped Proton

(Heidelberg, Max Planck Inst. ; U. Heidelberg (main) ; Darmstadt, GSI) ; Walz, J. (Mainz U., Inst. Phys. ; Helmholtz Inst., Mainz)
Spin transitions of an isolated trapped proton are observed for the first time. The spin quantum jumps are detected via the continuous Stern-Gerlach effect which is used in an experiment with a single proton stored in a cryogenic Penning trap. [...]

Hadronic light-by-light contribution to $(g-2)_\mu $ from lattice QCD: a complete calculation
/ Chao, En-Hung (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA) ; Hudspith, Renwick J. (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA) ; Gérardin, Antoine (Marseille, CPT) ; Green, Jeremy R. (CERN) ; Meyer, Harvey B. (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA ; Helmholtz Inst., Mainz ; Darmstadt, GSI) ; Ottnad, Konstantin (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA)
We compute the hadronic light-by-light scattering contribution to the muon $g-2$ from the up, down, and strange-quark sector directly using lattice QCD. Our calculation features evaluations of all possible Wick-contractions of the relevant hadronic four-point function and incorporates several different pion masses, volumes, and lattice-spacings.

Mainz, PRISMA ; Mainz U., Inst. Phys. ; Darmstadt, GSI ; CERN)
We compute the hadronic running of the electromagnetic and weak couplings in lattice QCD with $N_{\mathrm{f}}=2+1$ flavors of $\mathcal{O}(a)$ improved Wilson fermions. Using two different discretizations of the vector current, we compute the quark-connected and -disconnected contributions to the hadronic vacuum polarization (HVP) functions $\bar{\Pi}^{\gamma\gamma}$ and $\bar{\Pi}^{\gamma Z}$ for Euclidean squared momenta $Q^2\leq 7\,\mathrm{GeV}^2$.

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.

Cooling of particles to mK-temperatures is essential for a variety of experiments with trapped charged particles. However, many species of interest lack suitable electronic transitions for direct laser cooling. [...]

/ PANDA Cherenkov Group Collaboration
The PANDA experiment at the international accelerator Facility for Antiproton and Ion Research in Europe (FAIR) near GSI, Darmstadt, Germany will address fundamental questions of hadron physics. Excellent Particle Identification (PID) over a large range of solid angles and particle momenta will be essential to meet the objectives of the rich physics program. [...]
