Tetraneutron: A New Resonant State of Matter?

Tetraneutron, as the name suggests, is a hypothesized cluster of four neutrons bounded together as a single and compact stable system. It is generally believed that the tetraneutron state is not a long-lived phenomenon and would be observed for a temporary period which is less than a billionth of a trillionth of a second and ultimately gets decayed. Scientists call this state a resonance, as viewed from the window of particle physics. Also, from the theoretical standpoint, the existence of this 4-neutron state is not much supported by the standard mainstream models of nuclear forces and its physical existence would also mean that the foundations of our understandings regarding nuclear forces and their interactions would have to be significantly revised.

Now, a team of researchers from the Technical University of Darmstadt in Germany has published a paper in Nature...

Predictions of theoretical physics can’t be proved in a true sense but can only be verified to accurate levels of precision through experimental tests and modelling. There are several theories being proposed by people in the scientific community to explain the features of a particular phenomenon but only a few get lucky and stand the test of time. Quantum electrodynamics (QED) is one of the most precise theories of physics and is also the first theory that has achieved a proper and viable correlation between quantum mechanics and special relativity.

QED explains many features of quantum systems and their interaction. For example, electrons, which are elementary particles characterized by a negative charge and intrinsic spin, communicate with the atomic nucleus of an atom through the exchange of particles of light or photons. This interaction and interrelationship between the electron and...

Physicists Detect New Particle Which is a Dark Matter Candidate!

The standard model of particle physics is currently the best theory out there describing the fundamental constituents of nature. The model accurately describes the basic forces and their interactions with gravity being the only exception.

Despite the successes that the model boasts of, there are certain shortcomings of the theory that scientists around the world are trying to address and resolve. One of the key motivations is to find out the foundational building blocks of the so called Dark matter and Dark Energy which are believed to be made up of new unknown and undiscovered particles.

Recently, an interdisciplinary team of scientists led by physicists from Boston college in the US announced that they have discovered a new particle – or previously undetectable quantum excitation – known as the axial Higgs mode, a magnetic relative of the Higgs boson.

“The detection a decade ago...
