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

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.

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.

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

In an article published in the magazine Nature Physics, a team of researchers from Britain, the USA, Germany and Australia demonstrated for the first time the two cracks experiment in the timeline. Instead of spatial dispersion on a screen, the temporal crack created a dispersion in the light spectrum, and from the combination of another crack an interference pattern similar to the spatial pattern from the classic experiment was created. The experiment opens a window for the construction of time-varying optical instruments in a reliable and stable manner.

In recent years, physicists from around the world have been discussing the construction of a muon accelerator instead of other conventional accelerators based on protons or electrons. Such an accelerator has clear advantages in discovering new physics, but its construction is accompanied by many technological challenges. In this article I will review the words of Prof. Nima Arkani-Hamed from the Institute for Advanced Studies in Princeton on the need to build such an accelerator.

The upgrade is expected to last several years and will include the construction of a new building to house the upgraded accelerator. Permilab is also planning to build a new particle detector, which will be used to study the particles produced by the Tevatron.

Has a room temperature conductor finally been discovered? very doubtful The scientific community suspects the reliability of the findings and the reason for this is clear, the researcher who signed the disclosure claimed this in the past and was repelled by his colleagues claiming errors in the experiment.

Led by doctoral student Mamon Safdi and Professor Yaron Bromberg from the Hebrew University, an experiment was carried out that demonstrates for the first time a substantial advantage in characterizing materials using entangled photons over classical light. The experiment published in the prestigious journal Nature Physics measured the light from entangled photons that were backscattered from a non-static scatterer. The results of the experiment showed that entangled photons reduce the measurement error by four times than non-entangled light, thus breaking the Kramer-Rao barrier for classical light.

A team of researchers from Harvard University, MIT and Calcutta in collaboration with Google successfully simulated a traversable wormhole with the help of a quantum computer. The experiment performed on Google's quantum processor demonstrated the passage of information in the interlaced system. According to the principle of holography, the physics demonstrated in the experiment is the same as that of particles passing through wormholes. Although it was conducted on only nine qubits, the experiment is of great importance because it illustrates for the first time the possibility of testing quantum gravity with the help of entangled systems.
