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…

Monojet and direct detection constraints on real scalar dark matter: EFT and a simple UV completion

Arnab Roy, Michael A. Schmidt, German Valencia

We consider constraints that can be placed on certain invisible scalar particles through monojet studies at the LHC and compare them with those from direct detection experiments wh…
