Does The Higgs Violate Lepton Flavour Number? A CMS Result Tickles Wild Fantasies

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 by the ATLAS experiment- but that anomaly has vanished wi ...

Higgs Particle Behaves In A Way Consistent With The Standard Model- Maybe A Dark Supersymmetry?

The 37th International Conference on High Energy Physics (ICHEP) began last Thursday in Valencia, Spain with three days of parallel sessions, now moves on to plenary sessions until Wednesday, summing up the current state of the art in the field. The plenar ...

Self Quote Of The Week: Why You Can't Weigh Quarks Directly

In the process of revising a chapter of my book, I found a clip I would like to share here, as it contains an analogy I cooked up and which I find nice enough to be proud of. Well, two analogies, as you'll soon find out; here I am speaking of the cat ...

A Boron Cage Discovered?

In the 1980s, the discovery of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion in nanotechnology research. Now, there appears to be a new ball on the pitch- a cluster of 40 boron atoms forms a hollow molecular cage simila ...

Watching Electrons Jump Between The Fragments Of Exploding Molecules

Ultra-short X-ray flashes have enabled scientists to watch electrons jumping between the fragments of exploding molecules. The study reveals up to what distance a charge transfer between the two molecular fragments can occur, marking the limit of the mole ...

The SUSY-Inspiring LHC WW Excess May Be Due To Theoretical Errors

A timely article discussing the hot topic of the production rate of pairs of vector bosons in proton-proton collisions has appeared on the Cornell arxiv yesterday. As you might know, both the ATLAS and CMS collaborations, who study the 8-TeV (and soon 13-T ...

LUX-Zeplin Dark Matter Experiment, Two Others, Get Government Green Light

The U.S. Department of Energy has given the green light to the LUX-Zeplin (LZ) experiment, which wants to help figure out dark matter, an invisible substance that must make up a lot more of the universe than visible matter does. It is essentially a scient ...

A Universal Solution For A Quantum Three-Body Problem

Have physicists conquered the scaling behavior of exotic giant molecules? When a two-body relation becomes a three-body relation, the behavior of the system changes. The basic physics of two interacting particles is well understood but the mathematical des ...
