A huge facility in China will study the neutrino particles - mainly those generated from nuclear power plants

  • No comments
The facility, named JUNO, consists of a huge tank that surrounds an array of detectors. The container contains a substance that causes a scintillation which is recorded in the detectors and thus allows to identify a neutrino event, its type and mass, since the neutrino particles change into different types upon their formation

Non-grieving anions observed for the first time - a new technology for quantum computing?

  • 3 תגובות
The non-Abelian anions are quasi-particles with fascinating statistical and topological properties. Until recently, these particles were only theoretical, but now a research group from Harvard University has created them for the first time in the laboratory. The discovery may encourage companies in the field of quantum computing to use non-Abelian anions to create durable qubits.

A new theoretical analysis puts the probability that massive neutron stars harbor non-configurational quark nuclei between 80 and 90 percent. The result was achieved through massive computer runs using Bayesian statistical inference.

"This is the first measurement ever made of the free fall of antimatter (antihydrogen) atoms that directly shows that they really fall down," explained Prof. Eli Sharid from the Physics Department at Ben-Gurion University of the Negev, the member of the ALPHA collaboration group

Physicists have developed tools to discover unknown interactions between elementary particles. Are we on the way to a new physics?

Prof. Yael Shadami from the Faculty of Physics at the Technion focuses on the study of elementary particles including electrons, quarks, photons and gluons, and the interactions, or forces, that act between them. It tries to discover more elementary particles and interactions, beyond those described in the "standard model" of particle physics
A visual illustration of one of the collisions observed in the Atlas detector, and is an example of the type of processes we are looking for, and the signature they leave in our detectors. In this case a Higgs boson is created, together with another massive boson called Z (the carrier of the weak force). The blue cones and the yellow rectangles adjacent to them represent the pair of quarks into which the Higgs decayed, in this case they are of the magic type. The Z decays into two particles called muons, which can be identified by the red lines in the image. From the CERN website

For the first time, the Higgs boson was characterized by its decay into a pair of "magic" quarks

  • One response
Researchers from Tel Aviv University were able to describe for the first time a rare physical process that begins with the Higgs boson - the "divine particle" that was first observed about a decade ago - and eventually decays into a pair of rare elementary particles * New observations from the Sarn particle accelerator in Switzerland helped researchers understand the process more clearly
