Inclusive B-meson flavour-tagging algorithm at LHCb arxiv.org/abs/2508.20180 - This new algorithm improves the tagging power by 35% for B0 mesons and 20% for B0s mesons when compared to the combined performance of the existing LHCb flavour-tagging algorithms.

Search for the decay B⁰→ϕϕ arxiv.org/abs/2507.20945 - No significant signal is observed, and an upper limit on the branching fraction of 1.3 (1.4)×10⁻⁸ at 90 (95)% confidence level is set.

Cat or Particle Physics Experiment Do you know whether it's the name of the cat shown or of a particle physics experiment? Quiz made by William Barter, using cat photos provided by colleagues in the University of Edinburgh PPE group.

Is it the name of a cat or the name of a particle physics experiment?

I agree - I much prefer saying I work on beauty quarks! It sounds so special (But out of habit I do still say ‘top’!)

Thank you! ☺️ I hope so too!

Always good to be back at CERN! This time for the @lhcb.bsky.social collaboration week!

How lovely! I hope she is enjoying it

Hah! I haven’t heard that one!

Thank you! 😁

Thank you!

Thank you! Reverse-acronym? What am I missing…

Thank you, Franz. I will miss being part of the group!

Congratulations to @sliippr.bsky.social, who successfully passed her PhD viva yesterday!

Thank you! :D

I’m a Dr now!

Me, a woman in STEM:

A fantastic group to have been part of!

Up to three postdoctoral positions are available in our group @edinburghppe.bsky.social working on the LHCb experiment @lhcb.bsky.social #hep-jobs.

Today the LHCb collaboration posted a #preprint on the first observation of CP violation in baryons. What's the matter?

Spoiler alert: contains bananas 🍌

My first knitted colour work project - a hat with whales on! I knitted it with wool I bought in Iceland

The fluke of a humpback whale poking out of the water in the Faxaflói bay near Reykjavik

The fluke of a humpback whale in sunbeams through clouds, poking out of the water

Humpback whale spotted!

Thank you! 😁

Email notifications off - time for a well-earned post-thesis-submission holiday to Reykjavik! Hoping the volcano doesn’t explode 🌋

This information might be what I needed to take Ravelry more seriously

The LHCb experiment in watercolour :)

Observation of a new charmed baryon decaying to Ξc⁺π⁻π⁺ arxiv.org/abs/2502.18987 - Four states are observed with high significance. The Ξc(2923)⁺ baryon is observed for the first time, and is consistent with being the isospin partner of the previously observed Ξc(2923)⁰ state.

Registration is open for A-Level #physics school groups / individual students to attend our one-day Particle Physics Masterclass at the University of Manchester on April 4th 2025! We have 300 available slots for students & school groups who wish to attend. Sign up here: indico.global/event/4172/

Knitted myself an @lhcb.bsky.social jumper!! Thesis defence outfit sorted

Being able to knit and crochet is all fun and games until it’s time to move house and organise the wool stash
