Soft-Phonon-Driven Effective Inversion-Symmetry Crossover in Quantum Paraelectrics
Xiaojiang Li, Guodong Zhao, Fei Yang +6
Symmetry lays the foundation of condensed matter physics and its experimental manifestation provides fundamental insight into the collective behaviors of quantum materials. Optical…
Improved limits on a new in scenarios with the NA64 experiment at CERN
The NA64 Collaboration, Yu. M. Andreev, A. Antonov +53
Extensions of the Standard Model featuring an additional gauge symmetry provide a compelling framework linking the origin of neutrino masses to possible dark matter ca…
Development and integration of the NA64-DTC automation controller for the CERN "DESY Table" motorized platform
A. Antonov, A. Celentano, A. Marini +1
We report on the development, construction, and integration of a remote automation controller \texttt{NA64-DTC} for the so-called ``DESY Table'' motorised platform widely used at C…
Design and characterization of the POKERINO prototype for the POKER/NA64 experiment at CERN
Andrei Antonov, Pietro Bisio, Mariangela Bondì +3
The NA64 experiment at CERN H4 beamline recently started a high-energy positron-beam program to search for light dark matter particles through a thick-target, missing-energy measur…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Proof of principle for a light dark matter search with low-energy positron beams at NA64
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54
Thermal light dark matter (LDM) with particle masses in the 1 MeV - 1 GeV range could successfully explain the observed dark matter abundance as a relic from the primordial Univers…
