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…
