CSI: Neutrinos cast no shadows

Scientists solve neutrino mysteries by watching them interact with detectors — specifically, with the atomic nuclei in the detector material. Most of the time, a neutrino does not even shake hands with a nucleus. But when it does, the lightweight, neut...

Neutrinos: The ghost particle; Neutrinos from the sun

An introduction to the “Solar Neutrino Problem”, that is, why did scientists originally think that there was something really fishy going on with Wolfgang Pauli’s “little neutral one.” This post is a mash-up of two “Physics in a Nutshell” articles: Neu...

ArgoNeuT hits a home run with measurements of neutrinos in liquid argon

The ArgoNeuT experiment was the first ever to make cross-section measurements of neutrino and antineutrino (the neutrino’s antimatter counterpart) interactions resulting in a muon, a charged pion and any number of nucleons in the final state using argo...

Identifying lower-energy neutrinos with a liquid-argon particle detector

The ArgoNeuT experiment recently demonstrated for the first time that a particular class of particle detector — those that use liquid argon — can identify signals in an energy range that particle physicists call the “MeV range.” It’s the first substant...

From turkeys to turn-keys

The Illinois Accelerator Research Center (IARC) at Fermilab is on a mission to build a high-power, compact, superconducting electron beam accelerator that will serve all of these purposes. By Charles Thangaraj Read the article here.

Single-electron beam observed in IOTA for the first time

Just two months ago, in September 2018, the IOTA ring was successfully commissioned, and the program of the advanced beam physics studies has since begun. One of the most interesting scientific topics at IOTA will be studies of beams made … Continue re...

Superconducting film technology leads to record performance for low-frequency SRF cavity

Superconducting radio-frequency (SRF) cavities are the “muscle” of many modern particle accelerators. By cooling these devices to cryogenic temperatures (usually around 2 Kelvin, or minus 456 degrees Fahrenheit) and inputting electric power, SRF caviti...

MicroBooNE demonstrates use of convolutional neural networks on liquid-argon TPC data for first time

It is hard these days not to encounter examples of machine learning out in the world. Chances are, if your phone unlocks using facial recognition or if you’re using voice commands to control your phone, you are likely using machine … Continue reading →

Beautiful Higgs decays

The discovery of the Higgs boson in 2012 explained something no less foundational than how subatomic particles gain mass. The particle’s discovery marked the beginning of a comprehensive effort to measure its properties. In June 2018, the CMS collabora...

Breaking the symmetry between fundamental forces

At present scientists think that at the highest energies and earliest moments in time, all the fundamental forces may have existed as a single unified force. As the universe cooled just one microsecond after the Big Bang, it underwent a … Continue read...

The secret to measuring the energy of an antineutrino

Scientists study tiny particles called neutrinos to learn about how our universe evolved. These particles, well-known for being tough to detect, could tell the story of how matter won out over antimatter a fraction of a second after the Big … Continue ...

The secret to measuring an antineutrino’s energy

It is no secret that neutrinos change flavor or oscillate as they travel from one place to another, and that the amount they change depends on how much time they have to change. This time is directly related to the … Continue reading →

Which way did it go? A view from the top

Over the last decade, measurements by the CDF and DZero collaborations of how top quarks flee the scene of the crime, the so-called “forward-backward asymmetry,” caused quite a stir as they clashed with then state-of-the-art theoretical predictions for...
