Electroweak boson pairs offer new approach to searches for New Physics
Electroweak boson pairs offer new approach to searches for New Physics During the past decades, the Standard Model (SM) of particle physics that explains how the basic building blocks of matter interact is scrutinised by high energy physics experiments. Along with the remarkable success of the SM, there are compelling reasons to consider that at

007 reasons for physics beyond the Standard Model
007 reasons for physics beyond the Standard Model The 5th of July marks the fifth anniversary since the discovery of a Higgs boson at the LHC. Summarizing notes for a recent set of lectures at the Asia-Europe-Pacific School of High-Energy Physics, John Ellis reviews events leading to the discovery of the Higgs boson and what

CMS pixel upgrade: a truly global endeavor
CMS pixel upgrade: a truly global endeavor A new and upgraded pixel detector has just been installed in the heart of CMS in this extended year end technical stop (EYETS 2016-17), marking the end of a five year long construction project. The CMS pixel detector that was replaced was performing very well. However, the upgrade

A Moriond Retrospective: New Results from the LHC Experiments
A Moriond Retrospective: New Results from the LHC Experiments Every March, particle physicists around the world take two weeks to promote results, share opinions and do a bit of skiing in-between. This is the Moriond tradition and the 52nd iteration of the conference took place this year in La Thuile, Italy. Each of the four

Searching for dark energy with particle colliders
Searching for dark energy with particle colliders 2 GeV. For one type of coupling this is eleven orders of magnitude more stringent than constraints obtained from cosmological and solar system tests, and excludes previously popular models that require the coupling scale to lie close to the dark energy scale, Λ ~ 10 -3 eV. These

Where is Supersymmetry?
Where is Supersymmetry? The original ideas The original ideas for introducing supersymmetry dates back in the 1960s when, in the context of hadron physics that was found to be approximately spin-flavour independent, a symmetry between mesons and baryons was proposed. These ideas, largely ignored at the time, found their way through mathematical investigations related to
