Why is the mass of the Higgs particle lighter than expected?

Researchers have built a model according to which the mass of the Higgs boson, which helps produce the mass of elementary particles, changed in the early universe, and is therefore much smaller than the standard model of particle physics describes

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

A breakthrough in predicting chaotic results in the three body system

  • 3 תגובות
New research from the Larkach Institute of Physics reveals a significant advance in chaos theory, by confirming in detail the flux-based statistical theory that predicts chaotic outcomes in non-hierarchical Newtonian three-body systems. This breakthrough has practical implications for fields such as celestial mechanics, astrophysics and particle dynamics.

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.

- Spin laser on an atomic scale: the image describes the laser resonator structure consisting of two types of nanoantenna structures. The radiation is trapped in the internal structure only (yellow). The active layer of the laser - a single atomic layer - is on the resonator. The laser beam is split into two beams by the opposite spins of the photons (light particles), which can be controlled with the help of the laser pump (credit: Scholardesigner co, LTD).

Positive spin - research at the Technion was selected as one of the breakthroughs in photonics in 2023

Caption: Above, azobenzene is a molecule that can change its shape with light. An azobenzene molecule switches between two forms under the influence of light. In the lower figure: a molecular cage containing the molecules of the photosensitizer azobenzene. The new mechanism is based on a supramolecular approach in which the molecules of azobenzene and the photosensitizer are locked together in a molecular cage. The limited space accessible to the caged molecules allows only the E-form, but not the Z-form of azobenzene, so this molecule is pushed out of the cage. Credit: Jonathan R. Church

Publication in Science magazine about a new discovery: using harmless light to change the shape of an azobenzene molecule within a supramolecular complex

Azobenzenes are versatile compounds with many potential uses, such as advancing technology through the production of tiny machines, as well as creating light-activated drugs. These molecules can be found in two different forms called "E" and "Z" which can be exchanged between them through irradiation. However, under irradiation conditions both forms are in equilibrium, which prevents optimal utilization for different applications
