From the BBC, October 27, 2021: Yesterday, the MIcroBooNE collaboration opened a new chapter in physics with the announcement of their results; the search failed to find the particle, known as the sterile neutrino.
Four complementary analyses by Fermilab’s MicroBooNE show no signs of a theorized fourth kind of neutrino known as the sterile neutrino. Its existence is considered a possible explanation for anomalies seen in previous physics experiments.
A new analysis of the South Pole-based telescope’s observations has all but ruled out several popular models of inflation.
From Sanford Underground Research Facility, October 25, 2021: SURF will be hosting a gameshow-themed event. as part of the virtual event, “Deep Talks: Are you smarter than a dark matter physicist?” on Thursday, Oct. 28, from 6 to 7 p.m. MT. All are invited to attend the event where the audience will take part in a quiz about dark matter and the LUX-ZEPLIN (LZ) dark matter experiment.
From Tech Start Ups, October 24, 2021: How antimatter can one day power a rocket into space. Former Fermilab physicist Gerald Jackson believes testing an antimatter-based propulsion spacecraft could be a reality by 2050 if the high energy costs to produce antimatter weren’t a factor.
In early October, crews completed the raise-bore drilling of the vertical ventilation shaft at the Lead, South Dakota, LBNF/DUNE project site and unexpectedly uncovered a geological treasure during the process.
From Fuentitech, October 19, 2021: Physicists have long wondered if muons, electrons, and other leptons make a difference other than mass. The latest LHCb results suggest that the answer may be “yes” by revealing two minor anomalies that continue the strange pattern of “lost” muons shown in recent data from the LHCb. In April, the Muon g-2 experiment at Fermilab also found a discrepancy from the Standard Model but future results may also shed light on these differences.
Olivier Napoly has worked internationally on a variety of accelerator and collider projects. At Fermilab, he works as a guest scientist, helping to build the PIP-II particle accelerator. As an accelerator physicist, Napoly focuses on every aspect of PIP-II’s construction from design to assembly.
Creating a hypersensitive dark matter detector in a clean lab more than a mile underground is no mean feat in and of itself. Add a closed border and COVID restrictions to the mix, and you have the scenario that Fermilab, SNOLAB and the SENSEI collaboration faced. Undeterred, they found a way to proceed with installation.
