Heterotic String Theory Suggests a QCD Axion Near 0.5 neV / Benabou, Joshua N. (LBL, Berkeley ; UC, Berkeley) ; Dainelli, Giulio Alvise (LBL, Berkeley ; UC, Berkeley) ; Reig, Mario (CERN) ; Safdi, Benjamin R. (LBL, Berkeley ; UC, Berkeley)
We show that in heterotic string theory -- and dual corners of the landscape including Type I string theory -- the QCD axion mass is bounded from below by $m_a \gtrsim 0.5$ neV, a direct consequence of the model-independent axion whose decay constant is fixed by the grand unified theory (GUT) gauge coupling.

Are PTA measurements sensitive to gravitational wave non-Gaussianities? / Cecchini, Chiara (Trento U. ; TIFPA-INFN, Trento ; Madrid, Inst. Estructura Materia) ; El Gammal, Jonas (Insubria U., Como) ; Franciolini, Gabriele (Padua U. ; INFN, Padua) ; Pieroni, Mauro (Madrid, Inst. Estructura Materia)
Observing non-Gaussianity in the timing residuals of Pulsar Timing Arrays (PTAs) has recently attracted attention as a potential discriminator between astrophysical and cosmological origins of the observed Gravitational Wave (GW) signal. [...]

Observation of the charmless purely baryonic decay $\mathinner{\mathitΛ^0_b\!\to \mathitΛ p \overline{p}}$ / LHCb Collaboration
A search for the charmless purely baryonic decay $\mathinner{\mathitΛ^0_b\!\to \mathitΛ p \overline{p}}$ is performed using proton-proton collision data recorded by the LHCb experiment at a centre-of-mass energy of $\sqrt{s}=13\,\text{TeV}$ and corresponding to an integrated luminosity of $6.0\,\text{fb}^{-1}$ [...]

Differential measurements of $\gamma\gamma\to\tau\tau$ and constraints on $\tau$-lepton electromagnetic moments in Pb+Pb collisions at $\sqrt{s_{_\text{NN}}} = 5.02$ TeV with ATLAS / ATLAS Collaboration
This paper presents the first differential fiducial measurements of $\gamma\gamma\to\tau\tau$ using 1.93 nb$^{-1}$ of Pb+Pb data at $\sqrt{s_{_\text{NN}}} = 5.02$ TeV recorded by the ATLAS detector. [...]

Study of Particle Fluence Effects on Collected Charge and Depletion Voltage of the ATLAS IBL Planar Pixel Sensors / ATLAS Collaboration
After ten years of operation at the LHC, the planar pixel sensors of the innermost barrel layer of the ATLAS Pixel detector have accumulated an average bulk damage fluence in excess of $2\times10^{15}$ 1 MeV-neutrons equivalent/cm$^2$. [...]
