My 2019 physics wrap-up

It’s been quite the year …

On the physics side, our search for heavy, charged long-lived particles in ATLAS using 2015 and 2016 data as well as several analyses I had been on the ATLAS editorial board for or was involved in as ATLAS PubCom reader got published this year.
We continued exploring a first-ever search for Soft Unclustered Energy Patterns (SUEPs) as a sign of Hidden Valley / Hidden Sector models, and I was invited to give a talk about searches for long-lived particles at the LHC at this year’s Frühjahrstagung of the Deutsche Physikalische Gesellschaft. I was able to join the Large Hadron Collider Physics Conference in Puebla, Mexico to talk about searches for long-lived particles as well as science communication in ATLAS and the International Particle Physics Outreach Group (IPPOG).
In addition, the long-standing community white paper on searches for long-lived particles beyond the Standard Model at the Large Hadron Collider is finally under journal review.

On the outreach side, obviously the CERN Open Days have been the most visible activity this year, while a lot of other projects went on behind the scenes. I finally manage to get the ATLAS mural at Point 1 at CERN a make-over, ten years after its initial creation. And the renovation of the ATLAS Visitor Centre is, despite a few unforeseeable delays, in full swing and we hope to reopen in early 2020.

Luckily I also had multiple chances to see ATLAS this year, due to the Open Days preparations as well as several outreach projects we are working on, from more professional underground virtual visits to a 360 degrees virtual visit to the cavern.

And in the spirit of the holidays and competing with lasts year’s pictures, also this year we put together some season-inspired pictures … you’ll see more of that in the coming days ;)

Last but not least, I also handed in my habilitation report a few weeks before Christmas.
Let’s see if that helps in finding a new job net year …

CERN Open Days

The CERN Open Days are already fading away, even though it was an adventure that already started in July 2018. I had the pleasure of coordinating the ATLAS activities for this 75k-visitors event together with Anna Sfyrla, Laetitia Bardo and a great team of about a dozen ATLAS members that helped us by coordinating one of our activities.

During the Open Days, which started with an underground-only family day on Friday afternoon and lasted until Sunday evening, almost 300 ATLAS members joined as volunteers to make the ATLAS activities – as far as I am concerned – a huge success.

Holidays by the sea

I just returned from holidays at both the North and the Baltic Sea.
One week each in Garding on Eiderstedt and Fährdorf on Poel.

We had a very nice time watching the water come and go at the North Sea, walking the mud flats and dikes, taking a boat trip to see seals, porpoises and other animals living the sea, visiting the wonderful Multimar Wattforum and other nice places. Had some good food (lot’s of fish) and a lot of wind and quite a bit of rain.

On Poel the weather changed for the better and we had beach time, sand-castle (or figures) building, paddling tours on the Breitling (Bay of Wismar) and lot’s of other things.

Here’s a few pictures from both seas, some of which also made it to my gallery.

This week, I had the pleasure of participating in the 7th edition of the Large Hadron Collider Physics Conference (LHCP) in Puebla, Mexico.

Besides talking about latest updates on “Searches for long-lived particles in ATLAS” and “Particle Physics Outreach as a Strategic Pillar for Society: A report from IPPOG”, as well as presenting posters on “Communicating ATLAS: adapting to an ever-changing media landscape” and “ATLAS Outreach: on the dissemination of High Energy Physics and Computer Sciences“, I also had the chance to see a – way too tiny – bit of Mexico during the week.

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 …

Spring conferences

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 ;)
