[Misión del Perú en Ginebra @PeruEnGinebra]

El representante peruano ante la ONU en Ginebra, Embajador Elmer Schialer, y su equipo, acompañaron la visita de la UTEC al Centro Europeo para la Investigación Nuclear (CERN), con sede en Ginebra, donde suscribieron un Memorando de Entendimiento que refuerza la cooperación científica y abre nuevas oportunidades para que estudiantes y académicos peruanos participen en el proyecto LHCb, que estudia las partículas subatómicas fundamentales y los orígenes del universo 🚀

Measurements of CP asymmetries and branching fractions of B⁻ decays to two charm mesons https://t.co/aBHBrOdzIy - There is no evidence of CP violation in any of the analysed decays. Additionally, two ratios between branching fractions of selected decays are measured.

The LHCb upgrade I https://t.co/SnuRuRj8fA - The LHCb upgrade represents a major change of the experiment to allow running at an instantaneous luminosity five times larger. Readout of all detectors into an all-software trigger is central to the new design.

Measurement of the mass difference and relative production rate of the Ωb⁻ and Ξb⁻ baryons https://t.co/fXThOAPZAm - The mass of the Ωb⁻ baryon is measured to be 6045.9±0.5±0.6MeV.

Associated production of prompt J/ψ and Υ mesons in pp collisions at √s=13TeV https://t.co/dkS6Sv9I7y - The cross-section of the associated production of prompt J/ψ and Υ(1S) mesons is measured to be 133±22±7±3pb, and that of prompt J/ψ and Υ(2S) mesons to be 76±21±4±7pb.

Evidence for the decays B⁰→D̅⁽*⁾⁰ϕ and updated measurements of the branching fractions of the B⁰→D̅⁽*⁾⁰ϕ decays https://t.co/9taNU9BT2n - The branching fractions are measured to be
ℬ(B⁰→D̅⁰ϕ) = (7.7±2.1±0.7±0.7)×10⁻⁷, ℬ(B⁰ → D̅*⁰ϕ)=(2.2±0.5±0.2±0.2)×10⁻⁶.

Measurement of Ξc⁺ production in pPb collisions at √s(NN)=8.16 TeV at LHCb https://t.co/uvsbvxMEq8 - The Ξc⁺ production cross-section, as well as the Ξc⁺ to Λc⁺ production cross-section ratio, are measured as a function of the transverse momentum and rapidity.

Last week we asked you to #AskAPhysicist anything related to #LHCRun3 and CERN…Today, we thank you for all the amazing questions!

We know that you want to know more about what sound particles make when they collide, the #StandardModel of particle physics, if AI is used at CERN, and where do particles go after collision, so stay tuned for part II of the video to find out all the answers.

For now, as the #LHC continues the new #physics season, watch physicists from the @ATLASexperiment @ALICEexperiment, @CMSExperiment and @LHCbExperiment , as they answer your questions in part I of our #AskAPhysicist series. #BeamTime

Precision measurement of CP violation in the penguin-mediated decay Bₛ⁰→φφ - https://t.co/2pTMMprhlj The results are combined with previous LHCb measurements, yielding ϕss̅s=−0.074±0.069 rad and |λ|=1.009±0.030, the most precise in a penguin-dominated B meson decay.

Study of charmonium decays to K⁰s Kπ in the B → (K⁰sKπ)K channels https://t.co/qvL2CHrMcu - New precise measurements of the ηc and ηc(2S) resonance parameters are performed. The first observation and branching fraction measurement of B+→χc0K0π+ is reported.

Test of lepton flavour universality using B⁰ → D*⁻τ⁺ν decays with hadronic τ channels https://t.co/oQe055Tzfq - The lepton universality test R(D*⁻)≡B(B⁰ → D*⁻τ⁺ν)/B(B⁰ → D*⁻μ+ν) is calculated as 0.247±0.015±0.015±0.012.

D*(2007)⁰→μ⁺μ⁻ in B⁻→π⁻μ⁺μ⁻ decays https://t.co/4uxXYy8TS3 - This is the first limit on the branching fraction of D*(2007)⁰→μ⁺μ⁻ and the first search for a rare charm-meson decay exploiting production via beauty decays.
