Two years have passed since the discovery of the Higgs boson (on July 4th, 2012), and the young particle still causes excitement. Originally it was the excess of Higgs decays to photon pairs as seen…

Among the many more-or-less boring news from the ICHEP conference (International Conference on High Energy Physics), which is presently going on in Valencia (Spain), one bit today is sending good…

A couple of weeks ago I reported here about the new measurement of the Higgs boson mass produced by the ATLAS experiment. That determination, which used the full dataset of Run 1 proton-proton…

In cosmology, cold dark matter is believed to be a form of matter which moves slowly in comparison with light and interacts weakly with electromagnetic radiation. It is estimated that only a minute…

In quantum physics, you can't precisely measure momentum and position simultaneously. They are an example of conjugate variables, connected by Heisenberg's Uncertainty Principle. There are…

Do you remember the top quark asymmetry measurements of CDF and DZERO ? A few years ago they caused quite some excitement, as both experiments were observing a departure from standard model…

By trapping a magnetic field with a strength of 17.6 Tesla, roughly 100 times stronger than the field generated by a typical fridge magnet, in a high temperature gadolinium barium copper oxide (…

You wouldn't think that mechanical force, like kicking a ball in the World Cup or embossing letters on a credit card, could process nanoparticles more subtly than the most advanced chemistry but a…

What is believed to be the smallest force ever measured, 42 yoctonewtons, has been detected by at the Lawrence Berkeley National Laboratory. A yoctonewton is one septillionth of a newton and there…

The Higgs boson was detected using its decay into bosons but scientists from the CMS experiment at  the Large Hadron Collider have found evidence for the direct decay of the Higgs…
