A little art project, inspired by particle physics collisions, that I have been fiddling around with for a while now. Here you can see “Collision #7”, one of the results of the current setup.
Just like in a collision in the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, particles of colour collide at high energy and create a seemingly chaotic pattern in the detector. Admittedly, the energies are nowhere near those at the LHC and unlike in (real) high-energy collisions the outgoing ‘particles’ are still those that went into the collision, but yet there is a few commonalities. It is also coloured particles that collide in the LHC and the conservation of energy and momentum holds also in the Colliding Colours setup (even on a classical level).
Unfortunately, due to the cancellation of my original flight to Mexico and the resulting late arrival, an extremely persistent jet lag waking we up at around 3am each day, and the fact that I already had to leave on Friday, there wasn’t really any time to explore much of Mexico. So I could only see a bit of Puebla’s city centre and – through the conference excursion – the archeological site of Teotihuacan.
Quite an intense week with lots of physics (see timetable), little sleep, lots of Mexican food and many people to meet. If only Mexico wasn’t a twelve-hour flight away …
March is spring-conference time and ATLAS has presented some very nice results at the Moriond meeting in La Thuile over the past couple of days (and so have other experiments). Along with these results and the related publications we’ve been putting out several Physics Briefings highlighting some of the most interesting results and a summary piece.
In parallel, I’m at the spring meeting of the German Physical Society in Aachen this week. Our annual week with hundreds of talks and updates on particle physics in Germany and in general, this year enriched by talks on didactics and artificial intelligence.
On Tuesday I gave an invited-talk on “Searches for long-lived particles as signs of new physics at the LHC”, trying to convince a more people to join the hunt for long-lived particles ;)
With the LHC turned off, LS2 will also be a great chance for anybody to visit ATLAS (starting from May this year). Last week I managed to renew my underground training and therefore had the chance to see our beauty myself (see pictures) after quite some time. Besides the visits there is also lot’s of other things happening this year … CERN Open Days, a new ATLAS Visitor Centre, lots of new results … just to name a few.
