Two key properties of neutrinos in the standard model of particle physics (SM) are that they are massless and “left-handed”, i.e. their spin is always opposite to their momentum. The observation of neutrino oscillations posed a big challenge to the c…

The first search for new physics using LHC data collected in Run 3 has been presented by CMS. It was shown during this year’s EPS conference in Hamburg and relied on both the new data and refinements of the trigger system made for Run 3. It marks the…

At the subatomic level, interactions between particles are mediated through the exchange of special particles, the force carriers. In the case of electromagnetism, the force is transmitted by photons. They connect particles with electric charge (elec…
