W Pairs From Double Parton Scattering

When I explain to the public (in this blog, or at public conferences or schools) how the Large Hadron Collider operates, I have to gloss over a lot of detail that is unnecessary to grasp the important concepts, which enable other discussions on interesting ...

Old-School Statistical Learning Tools Challenge Neural Networks In Physics Problems

Neural networks are everywhere today. They are used to drive vehicles, classify images, translate texts, determine your shopping preferences, or finding your quickest route to the supermarket. Their power at making sense of small or large datasets alike is ...

Artificial-Intelligence Assisted Design Of Experiments

Yes, I know- I have touched on this topic already a couple of times in this blog, so you have the right to be bored and surf away. I am bound to talk about this now and then anyway, though, because this is the focus of my research these days.  Recently I w ...

New Hadrons Decaying Into J/Psi Pairs

Physicists from the CMS experiment at CERN's Large Hadron Collider have used the total data sample of 13 TeV proton-proton collisions collected in the past few years to search for resonant decays of heavy hadrons into pairs of J/Psi mesons, and they f ...

The Magic Dimuon Decay Of B Mesons

To appreciate what B mesons are, and what is the magic of their behaviour, which is the topic of this article, I need to give you a three-paragraph introduction below. At the smallest distance scales, matter is made of quarks and leptons, which we consider ...

Exploiting Nuisances

Today I am back from one of the most interesting workshops I ever attended to, and I wish to share some thoughts I had on possible ways to enhance our research of new ideas for future particle detectors with you. Those ideas come from discussions with othe ...

If There Is An Arrow Of Time, How Might It Work?

To most physicists, time is a relative construct. A clock changes position in three real dimensions, the earth rotates. If the effects in the real world change, like gravity, so does the perception of time. That does not make time a 'fourth' dime ...

Up-to-date With The Big Bang, Mass, And Protons

Not all that much to do with Hank’s recent blog about the Galileo document that isn’t, but a note about how Einstein could be somewhat “pig-headed”, similar misunderstandings and new developments in contemporary fundamental physics. ...

XI ICNFP Conference And 2nd MODE Workshop

I arrived to Kolymbari, a nice seaside resort on the western coast of the Greek island of Crete, late yesterday night, and am now already immersed in the morning session of the XI edition of the International Conference on New Frontiers in Physics. This ev ...

Highlights From ATLAS

Bill Murray gave a nice summary of recent results from the ATLAS collaboration at the ICNFP conference this morning, and I will nit-pick a few graphs from his presentation to show the level of detail of investigations in subnuclear processes that the Large ...
