Compact Muon Solenoid on the lookout for new physics

With Run 3 of the Large Hadron Collider (LHC) just around the corner, the LHC experiments are still publishing new results based on the previous runs' data. Despite no new discoveries being announced, small deviations from ...

Discovery uncovers need for ammonia emission regulations

A discovery by former Carnegie Mellon Ph.D. student, Mingyi Wang, leading a large collaborative team, sheds light on one way new particles are forming in the upper troposphere. The study, published in Nature, reveals an unexpected ...

The standard model of particle physics may be broken, expert says

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is "When are you going to find something?" Resisting the temptation to sarcastically reply "Aside from the Higgs ...

New and surprising duality found in theoretical particle physics

A new and surprising duality has been discovered in theoretical particle physics. The duality exists between two types of scattering processes that can occur in the proton collisions made in the Large Hadron Collider at CERN ...

Dispersal strategies drive marine microbial diversity

Trade-offs between the benefit of colonizing new particles and the risk of being wiped out by predators allow diverse populations of marine microbes to exist together, shows a study published today in eLife.

Protons are likely smaller than previously believed

A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even believed that the Standard ...

The quantum field theory on which the everyday world supervenes

The laws of physics underlying everyday life are, at one level of description, completely known, and can be summarized in a single elegant—if quite complex—equation. That's the claim physicist Sean Carroll, an SFI Fractal ...
