CERN upgrade to LHCb experiment threatened by UK funding cuts – Physics World Upgrade to the UK-led project is unlikely to go ahead if UK funding cuts are not reversed

Seriously bleak news, especially for hadron physics (also the EIC is affected).

Unfortunately, I expect this only to be among the first of many sizable cuts to fundamental physics in the next years, due to desperate attempts to keep late-stage capitalism alive.

One-Loop QCD Corrections to $\bar{B}\to X_c \ell \barν_\ell$ in and Beyond the Standard Model We compute one-loop QCD corrections to the triple differential width of the inclusive decay $\bar{B} \to X_c \ell \barν_\ell$ including contributions from all relevant dimension-six operators in the W...

Paper day! With Gael Finauri we computed pQCD corrections to observables in inclusive B->Xc l nu decays beyond the Standard Model. This helps looking for New Physics in measurements made at B-factories. Plus, our closed-form expressions should make pheno analysis easier! arxiv.org/abs/2601.16129

Today LHCb presented a new measurement of the decay of a B meson into a K* and a μ+ μ- pair

Previous results disagreed with the Standard Model prediction for the branching fraction and angular distribution

The new measurement has almost twice as much data and still disagrees!

It looks like the only difference with 2024 is that data taking started later in the year, do you know why that is?

New Physics in inclusive semileptonic $B$ decays We study inclusive semileptonic $\bar{B}\to X_c \ell \barν$ decays ($\ell = e,μ$) in the presence of generic physics Beyond the Standard Model (BSM) that is heavy compared to the $b$-quark mass. Its e...

New paper is out! With G. Finauri, P. Gambino, M. Jung and S. Mächler we performed a first-of-its-kind test of New Physics in inclusive B->Xclv decays. This work is crucial to understand whether or not the Vcb puzzle originates from beyond the Standard Model effects! arxiv.org/abs/2507.22123

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?
