U.S. CMS physicists from Fermilab and associated universities collaborating under the umbrella of the LPC make up a team that is the first to perform a new kind of search for “stealthy” supersymmetry that does not result in an obvious signature of large energy imbalance. Instead, the LPC team is looking for collisions that result in an unusually large number of particles in the detector. CMS recently published a briefing explaining their analysis.
Asymmetry in the proton confounds physicists, but a new discovery may bring back old theories to explain it.
Fermilab scientist and University of Chicago professor of astronomy and astrophysics Craig Hogan gives perspective on how the Holometer program aims at a tiny scale — the Planck scale — to help answer one of the universe’s most basic questions: Why does everything appear to happen at definite times and places? He contextualizes the results and offers optimism for future researchers.
After more than 15 years of work, scientists at three DOE national laboratories have succeeded in creating and testing an advanced, more powerful superconducting magnet made of a niobium-tin compound for use in the next generation of light sources.
The MicroBooNE neutrino experiment at Fermilab has published a new measurement that helps paint a more detailed portrait of the neutrino. This measurement more precisely targets one of the processes arising from the interaction of a neutrino with an atomic nucleus, one with a fancy name: charged-current quasielastic scattering.
The NOvA experiment, best known for its measurements of neutrino oscillations using particle beams from Fermilab accelerators, has been turning its attention to measurements of cosmic phenomena. In a series of results, NOvA reports on neutrinos from supernovae, gravitational-wave events from black hole mergers, muons from cosmic rays, and its search for the elusive monopole.
The international Deep Underground Neutrino Experiment collaboration has published a paper about its capability for performing supernova physics. It details the kind of activity DUNE expects in the detector during a supernova burst, how DUNE will know once a supernova occurs and what physics DUNE will extract from the neutrinos. DUNE’s unique strength is its sensitivity to a particular type of neutrino called the electron neutrino, which will provide scientists with supernova data not available from any other experiment.
The MINOS+ and Daya Bay neutrino experiments combine results to produce most stringent test yet for the existence of sterile neutrinos.
The ArgoNeuT collaboration has published new measurements of the neutrino interaction channel critical for future experiments that seek to understand the difference between matter and antimatter in the world of neutrinos. Their paper presents new strategies for identifying electron neutrinos in liquid-argon neutrino detectors like ArgoNeuT.
Fermilab scientists have broken their own world record for an accelerator magnet. In June, their demonstrator steering dipole magnet achieved a 14.5-tesla field, surpassing the field strength of their 14.1-tesla magnet, which set a record in 2019. This magnet test shows that scientists and engineers can address the demanding requirements for a future particle collider under discussion in the particle physics community.
