My new position at Clermont-Ferrand came with funding for two students and two post-doctoral research assistants. I am glad to say that today, I am opening applications for the first post-doc position. The info is here and the deadline is 13 March: https://inspirehep.net/jobs/2634296 The successful applicant will work on searches for long-lived particles in ATLAS,Continue reading “Recruiting my first post-doc”

Last week, I officially started a new job as a Junior Professor at the Laboratoire de Physique de Clermont. The lab is part of the Université Clermont Auvergne, in Clermont-Ferrand in France: a busy student town nestling on the edge of the stunning Chaine des Puys range of ancient volcanoes. Clermont-Ferrand is also the birthplaceContinue reading “Start of a new era!”

One of the nice features of Particle Physics for Babies is that it comes with downloadable captions, so that even if you are no expert in particle physics, you can explain the pictures with confidence. Upon release, we had the captions in English, with translations into French and German available (kindly provided by Dr NicolasContinue reading “Spanish and Farsi translations for “Particle Physics for Babies”!”

The wait is finally over! Particle Physics for Babies, the outreach book for newborns themed on high energy physics, has landed at the CERN gift shop, and is also available from the ATLAS secretariat. You can also order a copy from me, online here. I wrote the book on the last day of my parentalContinue reading ““Particle Physics for Babies” arrives at CERN”

A “Physics News” article I co-wrote about ATLAS searches for long-lived particles is featured on the CERN News page! Take a look here! It features my own search (which I’ve posted about before) as well as two other searches which came out this year from the group I lead: one looking for long-lived “dark photons”Continue reading “Long-lived particle searches featured on CERN “news” page”

My latest paper is on the arXiv today, to be submitted to JHEP (Journal of High Energy Physics): https://arxiv.org/abs/2203.01009 Here is a simple explanation… The Standard Model of particle physics encapsulates our best understanding of the building blocks of the universe to date, but we know it’s incomplete: there must ne new physics to accountContinue reading “Searching for neutral long-lived particles with the full LHC run-2 dataset”

My latest paper preprint is out on the arXiv, submitted to the Sci Post Physics Core journal. https://arxiv.org/pdf/2202.05882.pdf We used an “analysis recycling” method combined with some artificial intelligence to figure out if new physics theories we compatible with the existing data from the LHC, using about 5-10x less computing power than might previously haveContinue reading “Using machine learning to explore new-physics models”

New paper out on the arXiv today, with Jonathan Butterworth, Suchita Kulkarni, and some talented UCL MSci students. http://arxiv.org/abs/2105.08494 “Dark Sector” models, in which a bunch of new particles (some of which could explain Dark Matter = DM) are connected to the particles we know about (the Standard Model = SM) only via their interactionContinue reading “Re-using old measurements to set new constraints on composite dark matter”

The latest paper I worked on is out on the arXiv today ! https://arxiv.org/abs/2103.01918 It’s a detector-corrected measurement of the four-lepton invariant mass spectrum at the LHC. A rich and varied assortment of Standard Model physics processes contribute to this spectrum, which make it a great place to search for deviations and signs of newContinue reading “Measuring the four-lepton invariant mass spectrum”
