To confidently discover new physics in the muon g−2 anomaly requires that data-driven and lattice-QCD calculations of the Standard-Model value agree, write Thomas Blum, Luchang Jin and Christoph Leh...
The first run of the muon g-2 experiment at Fermilab increases the tension between measurements and theoretical calculations to 4.2 standard deviations.
The TOOLS 2020 conference attracted around 200 phenomenologists and experimental physicists to work on numerical tools for dark-matter models, and more.
Experiments such as MADMAX, IAXO and ALPS II are expanding the search for axions and other weakly interacting ‘slim’ particles that could hail from far above the TeV scale.
CMS has released a new search for charginos and neutralinos, with sensitivity boosted by the use of parametric machine learning.
The 2020 update of the European strategy for particle physics forms the basis of CERN’s objectives for the next five years, explains CERN Director-General Fabiola Gianotti.
Experimentalists and theorists met from 16 to 19 November for the eighth workshop of the LHC's long-lived particles community.
The FIPs 2020 workshop was structured around portals that may link the Standard Model to a rich dark sector: axions, dark photons, dark scalars and heavy neutral leptons.
The presence of new virtual particles could be clearly signalled by a right-handed contribution to the photon polarisation.
In a recent CMS analysis researchers have challenged the Standard Model by investigating a previously unexplored leptoquark signature.
