Physicists discover exotic, new tetraquark particles that we have never seen before

There is a new exotic subatomic particle on the atomic destroyer. Physicists working with the CERN collaboration Large Hadron Collider Beauty (LHCb) have found a new form of the elusive four-quark particle called tetraquark that they have never seen before. The newly identified particle consists of four quarks of the same taste and, according to scientists, is likely to be …

Physicists discover inexplicable interactions between particles in the search for dark matter

Deep below the Gran Sasso Mountains in Italy, the world’s most sensitive dark matter experiment has made a surprising discovery. No, it is not dark matter. Instead, the experiment found significantly more particle interaction events than predicted by the standard model of particle physics. Instead of the 232 ± 15 low-energy events expected in the data for a year from …

CalTech physicists propose an innovative new experiment to detect dark matter

Since the 1980s, researchers have been experimenting with the search for particles that make up dark matter, an invisible substance that permeates our galaxy and universe. Embossed dark matter because it emits no light. It has been shown repeatedly that this substance, which makes up more than 80 percent of the matter in our universe, influences ordinary matter through its …

A frightening premiere: physicists create an exotic “fifth form of matter” on board the ISS

Enlarge /. This series of false-color images shows the formation of a Bose-Einstein condensate in the prototype of the Cold Atom Laboratory in NASA’s Jet Propulsion Laboratory when the temperature approaches absolute zero, the temperature at which atoms have almost no movement. Caltech physicists and the Jet Propulsion Laboratory have, for the first time, created a rare quantum state of …

Physicists weigh the origin of heavy elements

A look at the ISOLDE magnetic spectrometer at CERN. Photo credit: Argonne National Laboratory A long-standing mystery in the field of nuclear physics is why the universe is made of the specific materials that we see around us. In other words, why is it “this” stuff and not other stuff? Of particular interest are the physical processes that are responsible …

Physicists capture first footage of quantum knots unraveling in superfluid

Enlarge / Researchers captured the decay of a quantum knot (left), which after a few microseconds and finally turns into a spin vortex (right). Tuomas Ollikainen / Aalto University The same team who tied the first "quantum knots" in a superfluid several years ago have now discovered that the knots decay, or "untie" themselves, fairly soon after forming, before turning …

However, the physicists at the University of Bonn and the University of Cologne have …

Physicists can finally take a look at Schrodinger's cat without killing it forever

There could be a chance to reach a climax in Schrödinger's Cat – the famous cat-based thought experiment that describes the mysterious behavior of subatomic particles – without permanently killing the (hypothetical) animal. The unfortunate imaginary cat lives and lives dead in a box, or exists in a superposition of "dead" and "living" states just as subatomic particles coexist in …
