Instead of a single Big Bang bringing the universe into existence billions of years ago, cosmologists are starting to suspect there may have been a second, transformative event that could explain the vast abundance of suspected dark matter. As New Scientist reports, our recent glimpses into the earliest moments of the universe, just millions of […]

Cosmologists are starting to suspect there may have been a second, transformative event like the Big bang that could explain dark matter.

In the last decade, measurements of $b \to s \mu^+ \mu^-$ processes have shown intriguing discrepancies with respect to the Standard Model (SM) predictions.

The intense programme of EPS-HEP 2023 underlined the vibrancy and diversity of the field.

Much has been learned in recent years about particle polarisation and related topics, in particular thanks to measurements made at the LHC.

Results from many experiments were presented, many of which are building excitement for even more rigorous tests of the Standard Model.

This year’s conference focused on “Hot topics in particle physics and cosmology: theory facing experimental prospects”.

Roman Jackiw was one of the most brilliant and profound theorists of his generation.

Heavy neutral leptons (HNLs) are particles beyond the Standard Model (SM), typically introduced to explain the small observed neutrino masses. In this talk, we discuss the theory foundations of HNL extensions of the SM, as well as the present status of experimental searches for them at the LHC.

Ben Allanach is a professor of theoretical physics at the University of Cambridge. Before that he was a post-doc at LAPP (Annecy, France), CERN (Geneva, Switzerland), Cambridge (UK) and the Rutherford Appleton Laboratory (UK).
