New IceCube detection proves 60-year-old theory On December 8, 2016, a high-energy particle called an electron antineutrino was hurtling through space at nearly the speed of light. Normally, the ghostly particle would zip right through the Earth as if it weren’t even there.   But this particle just so happened to smash into an electron deep inside the South Pole’s glacial ice. The collision created a new particle, known as the W – boson. That boson quickly decayed, creating a shower of s...

LOS ALAMOS, N.M., March 9, 2021—Analysis of results from an experiment called MiniBooNE at Fermilab has provided yet more evidence that particles called...

Virtual Particles: What are they? The term “virtual particle” is an endlessly confusing and confused subject for the layperson, and even for the non-expert scientist. I have read many books for laypeople (yes, I was a layperson once myself, and I remember, at the age of 16, reading about this stuff) and all of them talk about virtual particles and not one of them has ever made any sense to me. So I am going to try a different approach in explaining it to you. The best way to approach this ...

5 MARCH, 2021 In the final part of the LHC Physics at Ten series, we look at the searches that go beyond our current understanding of the universe An event recorded during 2016 with the CMS detector that contains 10 jets (orange cones) and a muon (red line). (Image: CERN) Count all the known kinds of particles in the universe. Now double it. This is the promise of a family of theoretical models known as Supersymmetry, or SUSY for short. The notion of theories predicting a d...

Physicists Just Found 4 New Subatomic Particles That May Test The Laws of Nature PATRICK KOPPENBURG, THE CONVERSATION 5 MARCH 2021 This month is a time to celebrate. CERN has just announced the discovery of four brand new particles at the Large Hadron Collider (LHC) in Geneva. This means that the LHC has now found a total of 59 new particles, in addition to the Nobel prize-winning Higgs boson, since it started colliding protons – particles that make up the atomic nucleus along with neutron...

by Charles Mudede • Mar 5, 2021 at 10:00 am Shall we shake the universe? brightstars/gettyimages.com In the previous decade, there were only two major events in the science of physics. One was the detection of the Higgs boson by the Large Hadron Collider (LHC) in 2012. (The particle was needed to explain why particles have mass.) The other big event occurred in our very own (radioactive) backyard, at Hanfords Laser Interferometer Gravitational-wave Obs...

Monday 08 March 2021, 16:00- 17:00 If you have a question about this talk, please contact Sunny Vagnozzi. I will review how future measurements of primordial Non-Gaussianities in the CMB , Large Scale Structure and 21-cm cosmology can probe very heavy particle physics at inflationary energy scales. Intuitively, the production of heavy particles is due to the “Hawking temperature” of inflationary spacetime, and their measurement is via their decay into inflatons. Even greater mass reach is...

The theory of tiny particles isn't complete. But new discoveries are helping scientists expand it.

  Scientists working at the frontier of particle physics are proposing the existence of a theoretical exotic, ultra-light “boson star” with a mass billions of times smaller than that of the electron and thinking about seeking a ‘darker’ origin of the ripples in spacetime, at the same time proving the existence of a dark-matter particle. Theories about the origin of dark matter in the universe –one of the biggest questions in science–vary from suggesting that it may be older than th...
