Hello to those who found me here. I am a particle physicist at CERN working on the @lhcb.bsky.social experiment and on future accelerators. In particular I worry about sustainability.
I'm also chairing the advisory committee of the 12000 CERN users.

I do hope that nobody has been given or denied a job/promotion based on their SpringerNature citation counts in the past 15 years.

I heard the russian version of this joke two days ago. @zachweinersmith.bsky.social must be spying on my conversations. I see no other explanation.

On this day 50 years ago, John Ellis, Mary K. Gaillard and Dimitri Nanopoulos submitted the paper "A Phenomenological Profile of the Higgs Boson" which was first to tell experimentalists how to find the Higgs boson.

LHCb rocking kaon physics again.
Search for K⁰→π⁺π⁻μ⁺μ⁻ decays at LHCb arxiv.org/abs/2511.02619 - Upper limits are set for the first time on the branching fractions B(K⁰s→π⁺π⁻μ⁺μ⁻)<1.4×10⁻⁹ and B(K⁰L→π⁺π⁻μ⁺μ⁻)<6.6×10⁻⁷, at the 90% confidence level.

🤔 CMS also measure R(J/ψ) on the high side. That's the ratio of Bc⁺→J/ψτν to
Bc⁺→J/ψμν. LHCb saw an excess compared to the Standard Model, now CMS has it too.
