I'm still on time.. just coming out of a meeting down in the bowels of #CERN... happy International Day of Women and Girls in Science!! #WomenInScience #InternationalDayofWomenandGirlsinScience #IDWGIS2026

Interesting episode at the passport control done at the gate at Geneva Airport when the guy whispered "conasse" as he was displeased by something about me, assuming I would not understand this fine French word.. one of the perks of knowing more than your passport language... 😬

A Christmas tree in the open space of an office building at CERN

Will the whole building 104 at CERN be at the mercy of goblins if we still have Christmas decorations on? It could be fun 😆😂 #TwelfthNight

Come and work with us 🤩

Being Too Helpful At Work Can Hurt Your Career—Here’s How To Say No Women are more likely to take on behind-the-scenes duties at work—extra tasks like onboarding or event planning—and it's hurting their careers. Here's how to say no.

In a study of professors, women got 378 new work requests over 4 weeks vs 118 for men. Women spent more time on service, advising & teaching; men on research. Orgs should track who is taking extra duties & ensure they are rewarded and distributed fairly. www.forbes.com/sites/kimels...

Happy Easter (island) 😅

Just had three interesting days at the Beyond the Flavour Anomalies 2025 workshop in Rome: agenda.infn.it/event/44057/
Good to see lots of friends and some nice #UTfit plots 😍. By chance, Nicola Cabibbo would have had his 90th birthday yesterday..

Honoured and proud to be beta-tester of the amazing conference clock designed and built by @randomgenerator42.bsky.social.. looking forward to the upcoming summer conferences 😉

..and you can clearly see me in this picture waving my hand 😅

Breakthrough Prize – Breakthrough Prize Announces 2025 Laureates in Life Sciences, Fundamental Physics, and Mathematics

Congratulations to us 13000 winners of the 2025 Breakthrough Prize in Fundamental Physics! 🥳 breakthroughprize.org/News/91

@officialscalextric.bsky.social Carlos the caterpillar should visit the good site also!! 😅

Hi I'm Marcella. I have a PhD but I don't know how to tie my shoes. 🤪

* had to stop three times during my #parkrun this morning 😬

Poster of the event. It reads "Celebrate IWD with the women of QMUL Faculty of Science and Engineering. 5th March 2025, 15:00-17:00, G.O. Jones Lecture Theatre. It shows the profile pictures of speakers Jessica Agnew-Blais and Marcella Bona, and chair Claudia Garetto.

Ahead of the International Women's Day 2025, we organised an interesting, intense, enlightening and fun event, led by Professor Claudia Garetto.. www.seresearch.qmul.ac.uk/pce/iwd25/
Hopefully the first of a long series 🤩

Happy International Day of Women and Girls in Science!! Greetings from the SPSC meeting at @cern.bsky.social 🤩

Subsonica in concert at O2 Kentish Town

Subsonica in London! 🥰 Not sure I've ever seen so many Italians in the same place in UK 😅

recognising my absolute favourite place for fondue in Geneva..
vive Bains des Pâquis 😍

Annapaola de Cosa asked ChatGPT for a dark shower representation 🤣

Dark Showers Workshop Following up on the initial discussions during the Dark-showers session of the Roadmap of DM workshop at CERN earlier this year, we would like to organize a “distributed” workshop, with a first meetin...

The Dark Showers Workshop is kicking off now! See here indico.cern.ch/event/1470958/ 😎

Fun day going around #CERN with our @qmulspcs.bsky.social students! I guided them in @atlasexperiment.bsky.social and at the data centre, but then I played the visitor at @cmsexperiment.bsky.social 🥰

There is a very nice article on Physics Today about the many important contributions that Dr. Wu gave to physics, beyond her famous proof of parity violation experiment. A few examples include entanglement, angular correlations of entangled gamma-ray photons, and Bell inequalities.

Big #indico fan here... recently suggested its use for a faculty event organised by a mathematician and a biologist.. blew their minds 🤩

Congratulations Nathan!! 😍 #ProudSupervisor

Mile end parkrun banner with some runners getting ready on the background

Did my 35th #parkrun at Mile End today! In the meanwhile I'm waiting for my 25 t-shirt.. however the #evri courrier is terrible and I don't think I will ever get it.. 🙄

Yeah.. I have to say that I had quite some luck with sold-out events in the last month . It's a little uncharacteristic of my general level of luck.. I wonder if I should be worried.. 😅

The Macbeths in their final bow on the stage (David Tennant and understudy Jasmin Hinds)

Grateful to the lady who sold me at a significant discount her extra ticket for Macbeth with David Tennant (but unfortunately no Cush Jumbo) 😍 very intense performance 👏 www.haroldpintertheatre.co.uk/shows/macbeth

The mass distribution of W±h in the low-NN-score SRs (top) of the merged ℓ±ν bb̄ event categories. The term `Others' summarises events from tHjb, tWh, tt̄tt̄, and SM Vh production. The background prediction is shown after a background-only maximum-likelihood fit to data. The lower panels show the ratio of the observed to the estimated SM background. The shaded bands show the total post-fit uncertainty in the background. The expected signal contribution assuming mH± = 900 GeV, normalised to a cross-section times branching ratio (σsig × B) values of 1.8 pb, is shown as a dashed histogram.

New ATLAS analysis just out from our group: a first search for a possible charged Higgs boson decaying into a W boson and Standard Model Higgs boson 🥳 (spoiler!) No significant excess found, but new exclusion limits are obtained spanning masses up to 3.0 TeV 😎 atlas.web.cern.ch/Atlas/GROUPS...
