Lessons from the $B^{0,+}\to K^{*0,+}μ^+μ^-$ angular analyses

On the new LHCb angular analysis of $B \to K^* μ^+ μ^-$: Hadronic effects or New Physics?

The new angular analysis of the decay $B \to K^* \ell^+ \ell^-$ recently presented by the LHCb Collaboration still indicates some tensions with the Standard Model predictions. There are several ongoing analyses to solve the problem of separating hadronic and New Physics effects in this decay, but the significance of the observed tensions in the angular observables in $B \to K^* μ^+μ^-$ is still dependent on a theory guesstimate of the hadronic contributions to these decays. Using the new data from LHCb we offer two tests which make a statistical comparison to determine whether the most favoure…

Model independent analysis of the angular observables in $B^{0} \to K^{*0} μ^+ μ^-$ and $B^{+} \to K^{*+} μ^+ μ^-$

We analyse the results recently presented on the $B^{+} \to K^{*+} μ^+ μ^-$ angular observables by the LHCb Collaboration which show indications for New Physics beyond the Standard Model. Within a model-independent analysis, we compare the fit results with the corresponding results for the angular observables in $B^{0} \to K^{*0} μ^+ μ^-$.

Towards a complete angular analysis of the electroweak penguin decay $Λ^0_b\to p h^-\ell^+\ell^-$

We investigate the rare electroweak penguin transition $b \to s \ell^+ \ell^-$ though angular analyses in baryonic $b$-decays. Instead of performing likelihood fits, that might suffer from ambiguity issues, we employ the moments technique, which is a simple counting experiment. The method is known to be robust under low statistics conditions and avoids the ambiguity problem by construction. We provide the full set of 32 orthonormal moments for $Λ^0_b\to p h^-\ell^+\ell^-$, where $h\in\{π,K\}$, for a polarized $Λ^0_b$ and the dihadron system $[ph]$ being in a spin-1/2 state.

Angular and polarization trails from effective interactions of Majorana neutrinos at the LHeC

We study the possibility of the LHeC facility to disentangle different new physics contributions to the production of heavy sterile Majorana neutrinos in the lepton number violating channel $e^{-}p\rightarrow l_{j}^{+} + 3 jets$ ($l_j\equiv e ,μ$). This is done investigating the angular and polarization trails of effective operators with distinct Dirac-Lorentz structure contributing to the Majorana neutrino production, which parameterize new physics from a higher energy scale. We study an asymmetry in the angular distribution of the final anti-lepton and the initial electron polarization effec…
