SUMMARY:IceCube Neutrino Observatory
DESCRIPTION:The IceCube Neutrino Observatory (or simply IceCube) is a neutrino observatory constructed at the Amundsen–Scott South Pole Station in Antarctica\, the project is a recognized CERN experiment (RE10). \nIts thousands of sensors are located under the Antarctic ice\, distributed over a cubic kilometre. Similar to its predecessor\, the Antarctic Muon And Neutrino Detector Array (AMANDA)\, IceCube consists of spherical optical sensors called Digital Optical Modules (DOMs)\, each with a photomultiplier tube (PMT) and a single-board data acquisition computer which sends digital data to the counting house on the surface above the array. IceCube was completed on 18 December 2010. DOMs are deployed on strings of 60 modules each at depths between 1\,450 and 2\,450 meters into holes melted in the ice using a hot water drill. IceCube is designed to look for point sources of neutrinos in the teraelectronvolt (TeV) range to explore the highest-energy astrophysical processes. In November 2013 it was announced that IceCube had detected 28 neutrinos that likely originated outside the Solar System. \nLinks:\nIceCube Neutrino Observatory \nIceCube: the coolest way to detect neutrinos (TV The Royal Institution) \nIceCube: the coolest way to detect neutrinos \nANITA experiment \nOur galaxy seen through a new lens: neutrinos detected by IceCube \n[LIVE] Observation of high-energy neutrinos from the Galactic plane

SUMMARY:LK-99 : a superconductor at room temperature - publications
DESCRIPTION:LK-99 (from the Lee-Kim 1999 research) is a potential room-temperature superconductor with a gray-black appearance\, It is said to have a hexagonal structure that is slightly modified from lead‒apatite by adding small amounts of copper. \nA team from Korea University led by Sukbae Lee (이석배) and Ji-Hoon Kim (김지훈) began studying this material in 1999. According to their claims\, LK-99 acts as a superconductor at temperatures below 400 Kelvin (K) and at ambient pressure. As of 6 August 2023\, the scientific community has not validated the superconductivity of LK-99 at any temperature through peer-reviewed processes or independent replication by other research groups. One preprint by a team from Southeast University\, China has reported an observation of zero resistance at 110 K. However the absence of a well-defined phase transition\, absence of the Meissner effect (a defining characteristic of superconductors)\, and the unique conditions under which these results were obtained raised doubts about the validity of the claim. Multiple other independent research teams are currently attempting to replicate the work of the South Korean team. Results are expected in August 2023\, as the process of producing the material is said to be straightforward. The initial studies announcing the discovery of LK-99 were uploaded to the open-access repository of electronic preprints\, arXiv. Lee later claimed the uploaded preprint papers were incomplete\, and coauthor Hyun-Tak Kim (김현탁) stated that one of the papers contained defects. \n \n\nMeissner Effect or Bust: Day 12 \nIt might be a bust… we may be over… \nPositives first!

SUMMARY:Neutrino Summer Lecture series
DESCRIPTION:The Neutrino Physics Center Summer Lectures are informal presentations for students at all levels interested in finding out more about neutrino physics in general\, with some emphasis on neutrino experiments being carried out at Fermilab. \nThe lectures are geared towards undergraduate and graduate students. Regularly scheduled Neutrino University lectures will be held on Wednesdays\, with options for both in-person and Zoom attendance. Please subscribe to our mailing list to get lecture announcements and Zoom connection information here (the name of the mailing list is “NEUTRINO_UNIVERSITY”). \nLinks:\nNeutrino Summer Lecture series

SUMMARY:#gminus2 New results from the Muon g-2 experiment at Fermilab - Publication / Scientific Seminar
DESCRIPTION:Muon g-2 doubles down with latest measurement\, explores uncharted territory in search of new physics. \nPhysicists now have a brand-new measurement of a property of the muon called the anomalous magnetic moment that improves the precision of their previous result by a factor of 2. An international collaboration of scientists working on the Muon g-2 experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory announced the much-anticipated updated measurement on Aug. 10. This new value bolsters the first result they announced in April 2021 and sets up a showdown between theory and experiment over 20 years in the making. “We’re really probing new territory. We’re determining the muon magnetic moment at a better precision than it has ever been seen before\,” said Brendan Casey\, a senior scientist at Fermilab who has worked on the Muon g-2 experiment since 2008. \nPhysicists describe how the universe works at its most fundamental level with a theory known as the Standard Model. By making predictions based on the Standard Model and comparing them to experimental results\, physicists can discern whether the theory is complete — or if there is physics beyond the Standard Model. Muons are fundamental particles that are similar to electrons but about 200 times as massive. Like electrons\, muons have a tiny internal magnet that\, in the presence of a magnetic field\, precesses or wobbles like the axis of a spinning top. The precession speed in a given magnetic field depends on the muon magnetic moment\, typically represented by the letter g; at the simplest level\, theory predicts that g should equal 2.  \nThe difference of g from 2 — or g minus 2 — can be attributed to the muon’s interactions with particles in a quantum foam that surrounds it. These particles blink in and out of existence and\, like subatomic “dance partners\,” grab the muon’s “hand” and change the way the muon interacts with the magnetic field. The Standard Model incorporates all known “dance partner” particles and predicts how the quantum foam changes g. But there might be more. Physicists are excited about the possible existence of as-yet-undiscovered particles that contribute to the value of g-2 — and would open the window to exploring new physics. \nThe new experimental result\, based on the first three years of data\, announced by the Muon g-2 collaboration is:\ng-2 = 0.00233184110 +/- 0.00000000043 (stat.) +/- 0.00000000019 (syst.) \nThe measurement of g-2 corresponds to a precision of 0.20 parts per million. The Muon g-2 collaboration describes the result in a paper that they submitted today to Physical Review Letters. With this measurement\, the collaboration has already reached their goal of decreasing one particular type of uncertainty: uncertainty caused by experimental imperfections\, known as systematic uncertainties.  \nLinks:\n#gminus2 Press Conference: First results from the Muon g-2 experiment at Fermilab

SUMMARY:Ghost particle: The neutrino's impact on cosmic science (TV webcast)
DESCRIPTION:Discover the power of neutrinos\, the ghost particle that could answer some of the greatest mysteries in the Universe. \nAn in-depth exploration of the elusive world of neutrinos. James Riordon guides us through the history and science behind the pursuit of the ghostly subatomic particle\, the neutrino. With approximately 100 trillion neutrinos passing through us every second\, these particles hold the key to unlocking some of the Universe’s greatest mysteries. From the discovery of neutrinos and their role in illuminating the Universe through neutrino telescopes to the challenges of detecting this elusive particle\, this lecture explores the science behind the ghost particle. Additionally\, we will explore the potential of neutrinos to answer some of the biggest questions in the universe\, including the composition of dark matter and the Universe’s origin. This is a unique opportunity to gain a deeper understanding of the science behind the neutrino and its impact on our understanding of the cosmos. \nLinks:\nGhost particle: The neutrino’s impact on cosmic science
