We present a systematic global analysis of dineutrino modes b → qν$$ \overline{\nu} $$ ν ¯ , q = d, s, and charged dilepton b → qℓ+ℓ− transitions. We derive improved or even entirely new limits on dineutrino branching ratios including decays B0→ (K0, Xs)ν$$ \overline{\nu} $$ ν ¯ , Bs→ ϕν$$ \overline{\nu} $$ ν ¯ and B0→ (π0, ρ0)ν$$ \overline{\nu} $$ ν ¯ from dineutrino modes which presently are best constrained: B+→ (K+, π+, ρ+)ν$$ \overline{\nu} $$ ν ¯ and B0→ K*0ν$$ \overline{\nu} $$ ν ¯ . Using SMEFT we obtain new flavor constraints from the dineutrino modes, which are stronger than the corresponding ones from charged dilepton rare b-decay or Drell-Yan data, for eτ and ττ final states, as well as for μτ ones in b → s processes. The method also allows to put novel constraints on semileptonic four-fermion operators with top quarks. Implications for ditau modes b → sτ+τ− and b → dτ+τ− are worked out. Even stronger constraints are obtained in simplified BSM frameworks such as leptoquarks and Z′-models. Furthermore, the interplay between dineutrinos and charged dileptons allows for concrete, novel tests of lepton universality in rare B-decays. Performing a global fit to b → sμ+μ−, sγ transitions we find that lepton universality predicts the ratio of the B0→ K*0ν$$ \overline{\nu} $$ ν ¯ to B0→ K0ν$$ \overline{\nu} $$ ν ¯ (B+→ K+ν$$ \overline{\nu} $$ ν ¯ ) branching fractions to be within 1.7 to 2.6 (1.6 to 2.4) at 1σ, a region that includes the standard model, and that can be narrowed with improved charged dilepton data. There is sizable room outside this region where universality is broken and that can be probed with the Belle II experiment. Using results of a fit to B0→ μ+μ−, $$ {B}_s^0 $$ B s 0 →$$ \overline{K} $$ K ¯ *0μ+μ− and B+→ π+μ+μ− data we obtain an analogous relation for |∆b| = |∆d| = 1 transitions: if lepton universality holds the ratio of the B0→ ρ0ν$$ \overline{\nu} $$ ν ¯ to B0→ π0ν$$ \overline{\nu} $$ ν ¯ (B+→ π+ν$$ \overline{\nu} $$ ν ¯ ) branching fractions is within 2.5 to 5.7 (1.2 to 2.6) at 1 σ. Putting upper limits on $$ \mathcal{B} $$ B (Bs→ ν$$ \overline{\nu} $$ ν ¯ ) at the level of 10−5 and $$ \mathcal{B} $$ B (B0→ ν$$ \overline{\nu} $$ ν ¯ ) below 10−6 would allow to control backgrounds from (pseudo-)scalar operators such as those induced by light right-handed neutrinos.

“…These transitions constitute powerful probes for New Physics (NP) contributions beyond the SM that can appear in competing diagrams and significantly affect branching fractions and angular distributions of b → s + − decays. Recent studies of b → s + − decays have observed tensions with SM predictions in measurements of branching fractions [1][2][3][4][5][6], angular observables [7][8][9][10][11][12][13] and tests of lepton universality [13][14][15][16][17][18][19][20][21]. One of the most significant deviations from SM expectations is observed in the determination of the branching fraction of B 0 s → φµ + µ − decays [6].…”

An angular analysis of the rare decay $$ {B}_s^0 $$ B s 0 → ϕμ+μ− is presented, using proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 8.4 fb−1. The observables describing the angular distributions of the decay $$ {B}_s^0 $$ B s 0 → ϕμ+μ− are determined in regions of q2, the square of the dimuon invariant mass. The results are consistent with Standard Model predictions.

The coupling of the electroweak gauge bosons of the Standard Model (SM) of particle physics to leptons is flavour universal. Experimental tests of this principle are highly sensitive to New Physics particles which couple differently among the leptonic families. The flavour anomalies that have been observed could imply the existence of lepton-flavour violating -hadron decays. Recent results in the study of rare decays in the → / sector from the ATLAS, CMS and LHCb collaborations are presented. Measurements of the branching fraction in 0 and Ξ − decays, study of the angular properties of 0 , + and 0 decays, and test of the lepton flavour universality via + → + + − processes are discussed in these proceedings.
