My 2019 physics wrap-up

ATLAS, CERN, Outreach, Physics

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

CERN, Geneva, LEGO, Outreach

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.

Spring conferences

Aachen, ATLAS, CERN, Germany, LHC, LLP, Physics

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 ;)

Visiting ATLAS

ATLAS, CERN, LHC, Outreach, Physics

With loads of data – collected during the past four years of Run 2 – in our pockets, ATLAS managed to produce a multitude of very interesting results and has now started Long Shutdown 2 (LS2), a two-year-long maintenance and upgrade phase to prepare ATLAS for the future. The latter includes both Run 3, coming up in 2021, and the high luminosity Large Hadron Collider (HL-LHC) scheduled for 2026. We’ll be covering all the upgrade activities on the ATLAS website over the coming months.

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.

ATLAS Visitor Centre reborn

ATLAS, CERN, Outreach

In case you happen to run an exhibition design company, why don’t you have a look at my first ever European CERN price enquiry for the “Design and Construction of the new ATLAS Visitor Centre“, released just a few minutes ago (deadline 19 November 2018).

ATLAS has been thinking about a new ATLAS Visitor Centre (current version seen in the picture above) for a couple of years already, but it seems we are finally getting close. I had the pleasure of learning how to prepare the relevant documents and the politics behind them (thanks to those that helped me) and will continue to lead this effort from the ATLAS side. We hope to have a new Visitor Centre by summer 2019, well enough in time for next year’s CERN Open Days (14/15 September 2019).

I’m very much looking forward to what people will come up with and many more things to learn in the process …
