Physics

The Cornell arxiv is known to not accept preprints without a minimal screening of their contents. Still, I am sometimes led to wonder if a similar attention is paid to the liberty that authors at times take with the titles of their papers. I am officially ...

Standard Model: Evidence For Direct Decay Of The Higgs Boson Into Fermions

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 boson into fermions. If the Higgs particle can decay into both bosons and f ...

The Smallest Force Ever Measured

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 are approximately 3 x 10 23 yoctonewtons in one ounce of f ...

17.6 Tesla: Decade Old Superconductor World Record Broken

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 (GdBaCuO) superconductor, researchers not only beat the previo ...

Heisenberg's Uncertainty Principle: Conjugate Variables And Compressive Sensing

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 workarounds, such as "weak measurement," to me ...

In Nanostructures, Physics Sometimes Trumps Chemistry

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 current paper in Nature Communications describes a no ...

Not Only Top: Bottom Asymmetry Measured By CDF!

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 expectations. This could really be the place where one would first ...

Redefining Dark Matter- Wave Instead Of Particle

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 fraction of the matter in the Universe is baryonic matter ...

Higgs Boson Mass: CMS On Top!

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 collisions produced by the LHC in 2011-2012, became and remaine ...

New LHC Diboson Excesses Point To Light SUSY!

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 vibrations through the spine of many of the few phenomenolog ...
