EOS version 1.1: A Software for Flavor Physics Phenomenology

Nienke C. Balz, Carolina Bolognani, Marta Burgos Marcos +18

EOS is an open-source software package for a variety of computational tasks in flavor physics. In this article, we describe new developments for version 1.1 of this software and di…

Measurements of electroweak penguin $B$ decays with missing energy at Belle and Belle II

Lorenz Gärtner

Electroweak penguin $B$ decays with neutrinos or $τ$ leptons in the final state are sensitive probes of physics beyond the Standard Model. Using the full Belle and Run 1 Belle II d…

Test of lepton flavor universality with $B ˉ \to D^{()} τ^{-} ν ˉ_{τ}$ and $B ˉ \to D^{()} ℓ^{-} ν ˉ_{ℓ}$ decays at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +494

We test lepton flavor universality with a measurement of the branching-fraction ratios $R(D^{(*)}) \equiv \mathcal{B}(\bar{B} \rightarrow D^{(*)} τ^{-} \barν_τ)/\mathcal{B}(\bar{B}…

Joint LHCb--Belle II Prospects to Constrain New Physics in $B \to D^{(*)} τ ν$

Johannes Albrecht, Florian Bernlochner, Marco Colonna +5

Semileptonic $b \to c τ ν ˉ_{τ}$ decays are powerful probes of non-Standard-Model effects within an effective-field-theory (EFT) framework, but fully exploiting them in current and fu…

Constraints on invisible $B^{+} \to K^{+} X$ decays from the Belle II $B^{+} \to K^{+} ν ν ˉ$ measurement

Lorenz Gärtner, Nikolai Krug, Thomas Kuhr +3

The Belle II measurement of the branching fraction for $B^{+} \to K^{+} ν ν ˉ$ shows a $2.7 σ$ excess over the Standard Model prediction and motivates new-physics explanations such as ax…

Constructing model-agnostic likelihoods, a method for the reinterpretation of particle physics results

Lorenz Gärtner, Nikolai Hartmann, Lukas Heinrich +5

Experimental High Energy Physics has entered an era of precision measurements. However, measurements of many of the accessible processes assume that the final states' underlying ki…
