WHY are fundamental physicists so keen聽to undermine the very theories that聽are the bedrock of their success? It is a聽reasonable question to ask confronted with the excitement bubbling around anomalies that seem to be firming up at CERN鈥檚 LHCb experiment .

Protesters gathered outside the Houses of Parliament and marched to Downing Street to deliver a letter to Boris Johnson, demanding action on excess winter deaths. Tens of thousands of people, particularly the oldest and poorest, die each year due to cold homes and the inability to afford heating. (Photo by Vuk Valcic/SOPA Images/LightRocket via Getty Images)

Aperture

Bottom view of the LEGEND-200 liquid argon cryostat and the enclosing water tank. The inner walls of the water tank and the outer wall of the cryostat are covered with a wavelength-shifting mirror film. The purpose is to shift and reflect the light produced by muons via the Cherenkov effect in the water. The photons are detected by photosensors. The purpose of this detector component is to detect and identify cosmic ray muons, some of which still reach the experiment despite being located deep underground the Gran Sasso mountain. (fyi: The muon flux is reduced by a factor 106 (one million) by the rock). If not identified, the muon induced events could mimic the searched signal events.
