Hello. I am a @_nikhef physicist working on the @LHCbExperiment at the LHC at @CERN. Occasionally I write long #Threads on physics results which I find interesting. Here's a list.

Is @iarxiv_org down again? Now I don't even get the mailing.

Evidence for the decay B⁰→μ⁺μ⁻ ! The LHCb experiment sees the rarest B meson decay ever !
In the image below the big peak is Bₛ⁰→μ⁺μ⁻ . That was well known for 10 years. But to its left is the small contribution from the B⁰. One in 10 billion B⁰ proceed to two muons.

I wrote a longer thread 5 years ago after the last update x.com/PKoppenburg/st…
It took a while, but it was worth the wait. The measurement of the B⁰ₛ→μ⁺μ decay rate is out. #Thread

Bizarre. New @arxiv preprints are online, but the listings not. arxiv.org/list/hep-ex/new

Merci à Sotomo et la RTS d'avoir donné les détails sur l'incertitude du #sondage. C'est pas toujours le cas.
