The origin and size of the neutrinos masses is one of the unsolved mysteries in High energy physics. Their masses must be very small (< 1eV) in comparison to the other elementary particles: if the neutrino had the weight of a house mite, the top quark would have the mass of a sperm whale! For theorists, this hierarchy in the masses is really unsatisfying, and the question is if there is a mechanism that makes the neutrino mass automatically that small.

Susy edges

August 2nd, 2014 | by

Two weeks ago, the  SUSY conference took place in Manchester, and we already had a nice report from Mathieu and Jory here in our blog. However, I also want to draw your attention to this talk about an overview of CMS searches for supersymmetric particles at the LHC. Generic searches for supersymmetric particles depend mainly on two possible observations: in most supersymmetric scenarios, one has a lightest stable supersymmetric particle (that can play the role of the dark matter candidate). This particle, if produced at a collider like the LHC, does not decay any more (stable!) and does not leave any trace in the detectors. No trace? No! Read the rest of this entry »

Back from the SUSY conference

July 29th, 2014 | by

Jory and Mathieu are PHD students working on beyond the standard model physics. They presented their current projects (click and click) at the SUSY 2014 conference in Manchester last week. Read on about their experiences at the conference…

Are there leptoquarks?

July 16th, 2014 | by

leptoquarks
Leptoquarks are interesting objects: These (so far) hypothetical particles are able to connect a single Lepton and a single quark in one interaction. For triggering such an interaction, leptoquarks have to carry both lepton number (such as leptons) and baryon quantum number (such as quarks). Hence the name: Lept-o-quark.
