Physicists on CERN’s LHCb collaboration say they’ve observed three new exotic particles – X(4274), X(4500) and X(4700) – and also confirmed the existence of a fourth one, X(4140). According to the scientists, each of these particles contains two quarks and two antiquarks. View of the LHCb detector. Image credit: CERN. …

An international team of scientists, led by Dr. Niels Kjærgaard from the University of Otago in Dunedin, New Zealand, has used steerable ‘optical tweezers’ to split ultracold clouds of potassium-40 (40K) atoms and smash them together to directly observe a key principle of quantum mechanics – the Pauli exclusion principle. …

According to a team of physicists at Imperial College London (ICL), UK, it is possible to create a new form of light by binding light to a single electron, combining the properties of both.

Physicists from the NOvA collaboration have announced a new result that could improve our understanding of the behavior of neutrinos. NOvA detector. Image credit: Louise Suter / NOvA Collaboration. Neutrinos are tiny, nearly massless subatomic particles that travel at near-light speed. They have previously been detected in three types, called …

Recent findings by a team of experimental nuclear physicists in Hungary indicating the possible discovery of a new subatomic particle may be evidence of a fifth force of nature, according to a team of theoretical physicists at the University of California, Irvine. The discovery of a possible fifth force of …

A physicist at Griffith University in Australia has solved an anomaly of conventional physics and shown that a mysterious effect called ‘T violation’ could be the origin of time evolution and conservation laws. Dr. Vaccaro is challenging the conventional view of space and time to show how the world advances …

For the first time, physicists have discovered that in an extremely high magnetic field ‘massless’ Dirac electrons can acquire a mass.

An international team of physicists, led by the University of the Witwatersrand (UW) in Johannesburg, South Africa, predicts the existence of a new particle that might aid in the understanding of dark matter. Proton-proton collisions events in which two high energy electrons and two high energy muons are observed. Image …

Plutonium, a heavy, silvery metal with 15 isotopes that is produced by the neutron irradiation of natural uranium, is formidably complex element that does not always act as expected. New research published in the journal Physical Review B shows that plutonium does not share electrons when it bonds with fluorine …

The Universe is not spinning or stretched in any particular direction, according to a team of researchers from University College London and Imperial College London, UK. A massive cluster of yellowish galaxies, seemingly caught in a red and blue spider web of eerily distorted background galaxies, makes for a spellbinding …
