Measurement of the emittance of accelerated electron bunches at the AWAKE experiment / AWAKE Collaboration
The vertical plane transverse emittance of accelerated electron bunches at the AWAKE experiment at CERN has been determined, using three different methods of data analysis. [...]

Dark-Sector Search via Pion-Produced η and η′ Mesons Decaying Invisibly in the NA64h Detector / NA64 Collaboration
We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar η and η′ mesons in the NA64h experiment at the CERN SPS. Our novel technique uses the charge-exchange reaction of 50 GeV π- on nuclei of an active target as the source of neutral mesons. [...]

Experimental Observation of Motion of Ions in a Resonantly Driven Plasma Wakefield Accelerator / AWAKE Collaboration
We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. [...]

Application of a Camera Array for the Upgrade of the AWAKE Spectrometer / Senes, Eugenio (CERN) ; Cooke, David (Royal Holloway, U. of London) ; Mazzoni, Stefano (CERN) ; Pannell, Fern (Royal Holloway, U. of London) ; Turner, Marlene (CERN) ; Wing, Matthew (Royal Holloway, U. of London) ; Zevi Della Porta, Giovanni (CERN ; Lindau, Max Planck Inst.)
The first run of the AWAKE experiment successfully demonstrated the acceleration of an electron beam in the plasma wakefields of a relativistic proton beam. The planned second run will focus on the control of the emittance  of accelerated electrons, requiring an upgrade of the  existing spectrometer. Preliminary measurements showed that this might be achieved by improving the resolution of the scintillator and with a new design of the optical system. This contribution discusses the application of a digital camera array in close proximity of the spectrometer scintillator, to enable the accelerated electron beam emittance measurement..

First constraints on the L$_{μ}$− L$_{τ}$ explanation of the muon g-2 anomaly from NA64-e at CERN / NA64 Collaboration
The inclusion of an additional $U(1)$ gauge $L_\mu-L_\tau$ symmetry would release the tension between the measured and the predicted value of the anomalous muon magnetic moment: this paradigm assumes the existence of a new, light $Z^\prime$ vector boson, with dominant coupling to $\mu$ and $\tau$ leptons and interacting with electrons via a loop mechanism. The $L_\mu-L_\tau$ model can also explain the Dark Matter relic abundance, by assuming that the $Z^\prime$ boson acts as a ``portal'' to a new Dark Sector of particles in Nature, not charged under known interactions. [...]

Hosing of a long relativistic particle bunch in plasma / AWAKE Collaboration
Experimental results show that hosing of a long particle bunch in plasma can be induced by wakefields driven by a short, misaligned preceding bunch. Hosing develops in the plane of misalignment, self-modulation in the perpendicular plane, at frequencies close to the plasma electron frequency, and are reproducible. [...]

Filamentation of a Relativistic Proton Bunch in Plasma / AWAKE Collaboration
We show in experiments that a long, underdense, relativistic proton bunch propagating in plasma undergoes the oblique instability, that we observe as filamentation. We determine a threshold value for the ratio between the bunch transverse size and plasma skin depth for the instability to occur. [...]

Probing light dark matter with positron beams at NA64 / NA64 Collaboration
We present the results of a missing-energy search for Light Dark Matter which has a new interaction with ordinary matter transmitted by a vector boson, called dark photon ($A^\prime$). For the first time, this search is performed with a positron beam by using the significantly enhanced production of $A^\prime$ in the resonant annihilation of positrons with atomic electrons of the target nuclei, followed by the invisible decay of $A^\prime$ into dark matter.

Search for Light Dark Matter with NA64 at CERN / NA64 Collaboration
Thermal dark matter models with particle $\chi$ masses below the electroweak scale can provide an explanation for the observed relic dark matter density. This would imply the existence of a new feeble interaction between the dark and ordinary matter. [...]
