LHCb is one of the biggest experiments of the Large Hadron Collider (LHC) at CERN. It is designed to explore what happened just after the Big Bang.

Check out what Francesco unveiled about his PhD work at the LHCb Implications Workshop 2026!
In LHCb's search for more signals of CP Violation in charm physics, the decay of a charmed baryon was probed by our researchers. And last week the results were shown for the first time to the public! Watch the video and discover what we found! #lhcb #cern #particlephysics #charmphysics

Physicists’ are continuing to explore the Zeptoverse 🔎!
Hear from researchers at @unibarcelona , @cern , @imperialcollege , and @epflcampus why study rare decays of beauty hadrons, why are physicists excited about recent results and the new upgraded LHCb, and what do they love most about being apart of the LHCb Collaboration?

Another piece in the puzzle for the search for physics beyond our current theories!
This week at the Implications Workshop, LHCb announced a new measurement of the lepton flavour universality ratios R(D) and R(D*). In these measurements, the decay rates of a beauty meson into a charm meson, a lepton and a neutrino are compared for the different leptons. Statistical evidence for the violation of the universality between tau leptons and muons still persists after many years of measurements, including several from LHCb. If such a violation is confirmed, once measurements become more precise, it would be clear evidence for new physics. However, the threshold for discovering new physics is high: many complementary measurements are needed to confirm any deviations.
Here @lhcbexperiment and @uomphysics researcher Biljana Mitreska and @cern theorist Florian Herren discuss what this measurement is all about, why it's important, and how future measurements could pave the way to the long wished for confirmation of New Physics!

Interested in what is going on behind the scenes for LHCb to enter the zeptoverse 🤯?
Hear from three of our researchers from @dortmund_lhcb on what has been measured, why it is interesting and how the upgraded LHCb experiment has unlocked this measurement for the very first time.
Also learn what they love about being a part of the global LHCb collaboration 🧑🔬

Evidence for the rarest B meson decay yet! 🔍
Today at the LHC seminar, the LHCb collaboration at @CERN announced the first single-experiment evidence of a beauty meson containing a beauty and down quark decaying to two muons, with a probability of approximately one in ten billion. The faint evidence left by this decay in the first slide is shown as the green bump in the third slide. To date, this is the rarest process measured at the Large Hadron Collider and provides new insight into the interactions of fundamental particles.
This measurement has only been made possible by the recent upgrade of the LHCb detector, which has enabled the collection of five times more data per year while also improving the overall data quality. This measurement especially gains from the improved particle identification capabilities 🔬.
This particular decay is so interesting due to its rarity and relatively simple final state. This results in Standard Model predictions with impressive precision, that may be compared to the experimental results. In this case they agree, further bolstering the Standard Model’s impressive history of predictive power . This measurement analysed data recorded during 2024 and 2025, leaving additional data recorded in 2026 still to be included in the future 🕵️.

It all started in 2011. A workshop sparked by intriguing hints of unexpected matter-antimatter asymmetries in charm decays, bringing experimental and theoretical physicists together to discuss what these results could mean.
15 years later, the LHCb Implications Workshop is back for its 2026 edition!
Join Vava Gligorov, LHCb Physics Coordinator, who was also part of the very first edition, as he looks back at how it all began and welcomes everyone to this year's workshop.
Stay tuned for a week of new results, discussions and exciting physics!

Studying beautiful flavour transitions ✨
@cmsexperiment and @lhcbexperiment researchers #AtCERN have released their latest results on the rare transformation of a beauty quark into a strange quark and two muons.
The illustration shows the transformation of a bottom quark into a strange quark, a muon and an antimuon (b→sμ+μ-) via the weak interaction.
Read more about it on home.cern, link in our stories.

We recently took the amazing @particleclara underground to see our incredible @lhcbexperiment detector ✨
Sitting 104m underground, it’s the deepest of the four experiments on CERN’s Large Hadron Collider, and it is highly specialised to study a specific type of particle called beauty quarks ⚛️
➡️ Swipe to learn more about all the different parts of our detector.
🔔 And stay tuned to join Clara on her visit, and see LHCb up close!

The 121st LHCb Week has just come to an end. And what an amazing week it was! ✨
For the first time, the LHCb week took place in Vilnius 🇱🇹, bringing together collaborators from all over the world for a week of great talks, reports, a poster session, and important discussions about the future of LHCb, including Upgrade II.
And of course, there was plenty of time to enjoy the week together outside the meeting room too, from the welcome drink and the excursion to the Gala Dinner and DJ night. 🥂🎶
A big thank you to the LHCb group in Vilnius, all the sponsors who supported the event, the volunteers, and the city of Vilnius for the warm welcome and for making this such a memorable week.
It will be hard to top this one! 💙

The LHCb Experiment’s research is truly ground breaking ✨
In 2025, the LHCb Collaboration won the Breakthrough Prize in Fundamental Physics, recognising their significant contributions to our understanding of the Universe, along with the three other major experiments on the Large Hadron Collider at @cern 🏆🌌
But the impact doesn’t end there! The LHCb Experiment’s $500,000 share of the prize money was donated to the CERN & Society Foundation for grants to doctoral students to spend research time at CERN 🎓
🚨 But this prize-winning experiment is at risk 🚨
UKRI has pulled the UK’s funding contribution to the upcoming detector upgrade necessary for LHCb to operate beyond the early 2030s.

Ever wondered what it’s like to spend your summer at CERN? 👀☀️
For our summer students, it’s a few months of physics, coding, new challenges, new friendships... and probably getting lost in CERN at least once. 🔬💻🌍
We handed them the mic to tell you the rest. 🎤
