The Standard Model prediction for the rare decay B → X s ν ν ¯ $$ B\to {X}_s\nu \overline{\nu} $$

Journal of High Energy Physics
We present updated and comprehensive Standard Model predictions for the inclusive rare decay B → X s ν ν ¯ $$ B\to {X}_s\nu \overline{\nu} $$ . Using a state-of-the-art determination of the short-distance coefficient, including NLO QCD and electroweak ...

Rare charm decays at LHCb

The LHCb experiment collected the world's largest sample of charmed hadron decays. This data set allowed the LHCb collaboration to provide the most precise results for rare charm decays with two leptons in the final states.

Disentangling new physics in K → πν ν ¯ $$ K\to \pi \nu \overline{\nu} $$ and B → K K ∗ ν ν ¯ $$ B\to K\left({K}^{\ast}\right)\nu \overline{\nu} $$ observables

Journal of High Energy Physics
We investigate the possibility of disentangling different new physics contributions to the rare meson decays and through kinematic distributions in the missing energy .

Rare decays at LHCb

, 2016
Rare decays are flavour changing neutral current processes that are loop-suppressed in the Standard Model (SM). New particles in SM extensions can therefore give significant contributions, modifying branching fractions and angular distributions ...

B ¯ s , d 0 $$ {\overline{B}}_{s,d}^0 $$ → J/ψμ + μ − decays in QCD factorization

Journal of High Energy Physics
Motivated by the first LHCb searches for the rare B ¯ s , d 0 $$ {\overline{B}}_{s,d}^0 $$ → J/ψμ + μ − decays, we perform a detailed study of these processes within the QCD factorization formalism.

Effective field theory analysis of rare |∆c| = |∆u| = 1 charm decays

Journal of High Energy Physics
We perform a global analysis of |∆c| = |∆u| = 1 transitions using recent data on D 0 → μ + μ − , D + → π + μ + μ − , Λ c → p μ + μ − , and D 0 → π + π − μ + μ − decays, and work out constraints on new physics Wilson coefficients C 7 , 9 , 10 ′ $$ {C}_{7 ...

Rare $B$ decays at LHCb

, 2017
Rare decays are flavour changing neutral current processes that allow sensitive searches for phenomena beyond the Standard Model (SM). In the SM, rare decays are loop-suppressed and new particles in SM extensions can give significant contributions.

Rare Decays in LHCb

EPJ Web of Conferences, 2012
The rare B decays B(s)0 → μ+μ−, B0 → K*0μ+μ− and Bs0 → φγ are studied using up to ~ 0.41 fb−1 of pp collisions at √s = 7 TeV collected by the LHCb experiment in 2010 and 2011. A search for the decays B(s)0 → μ+μ− is performed with 0.41 fb−1.
