How much do dark matter particles weigh?

The Hindu  

Dark matter is an enigmatic invisible substance supplying five-sixths of the matter of the universe. In 1922, Dutch astronomer Jacobus Kapteyn studied the motion of stars neighbouring the Sun and concluded the density of “dark matter” must be 0.0003 solar masses per cubic light year. Now, since we know the local density of dark matter, the value of the unknown …

Peter Higgs, physicist who proposed the existence of the ‘God particle,’ dies at 94

Associated Press  

LONDON — Nobel prize-winning physicist Peter Higgs, who proposed the existence of the so-called “God particle” that helped explain how matter formed after the Big Bang, has died at age 94, the University of Edinburgh said Tuesday. Higgs’ work helps scientists understand one of the most fundamental riddles of the universe: how the Big Bang created something out of nothing …

Explained | The decade-long search for a rare Higgs boson decay

The Hindu  

Last week, physicists working with the Large Hadron Collider particle-smasher at CERN, in Europe, reported that they had detected a Higgs boson decaying into a Z boson particle and a photon. For example, this theory, called the Standard Model, says that a Higgs boson will decay to a Z boson and a photon 0.1% of the time. This means the …

The Hindu  

FOR Fermilab, the premier particle accelerator laboratory in Illinois, United States, April 7 seems to be a favourite date for coming up with bombshells that shake and threaten to topple the Standard Model of Particle Physics, an otherwise spectacularly successful theory that describes the universe in terms of fundamental particles and forces of nature. The experiment’s finding conclusively established with …

The Hindu  

THE new particle whose discovery was announced on July 4 at the European Organisation for Nuclear Research in Geneva is in all probability the highly elusive Higgs boson, which was being desperately sought by theoretical high-energy physicists for nearly four decades. It is only by measuring the characteristics of its decay via various final states into other subatomic particles according …

Is the LHC on the brink of discovering new physics?

The Hindu  

Once in a way, the world of physics is in a state of upheaval – experiments are carried out that reveal limitations to older, established theories, and new physics is born. Verge of discovery While the findings were not sufficiently strong to be counted as a discovery, CERN scientists were excited enough to reveal that if the anomaly they had …
