Search for axion-like particles decaying to two photons at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +450

Axion-like particles (ALPs) are predicted in many extensions of the Standard Model and provide a well-motivated portal between visible and hidden sectors through their coupling to…

Accelerating Discovery: Model-Agnostic Likelihoods for the Reinterpretation of Particle Physics Results and their Application to the Belle II $B^{+} \to K^{+} I^½ I^ˉ ½$ Measurement

Lorenz GÃ¤rtner

Experimental results in high-energy physics are inherently hypothesis-dependent, as collider analyses are designed to test specific theoretical frameworks. The proliferation of the…

First search for $B \to X_{s} I^½ I^ˉ ½$ decays

Belle II Collaboration, M. Abumusabh, I. Adachi +440

We report the first search for the flavor-changing neutral-current decays $B \to X_{s} I^½ I^ˉ ½$ , where $X_{s}$ is a hadronic system with strangeness equal to 1, in data co…

Constraints on invisible $B^{+} \to K^{+} X$ decays from the Belle II $B^{+} \to K^{+} I^½ I^ˉ ½$ measurement

Lorenz GÃ¤rtner, Nikolai Krug, Thomas Kuhr +3

Belle II measurement of the branching fraction for $B^{+} \to K^{+} I^½ I^ˉ ½$ shows a $2.7 I ¨ $ excess over the Standard Model prediction and motivates new-physics explanations such…

A search for feebly-interacting particles in $B$ decays with missing energy at Belle

Belle, Belle II Collaborations, : +406

We present a search for an invisible hidden-sector particle $X_{inv}$ , produced in $B^{0} \to D ˉ^{0} X_{inv}$ and $B^{\pm} \to h X_{inv}$ decays, where $h = I ¨ ^{\pm}$ ,…

Reinterpretation and preservation of data and analyses in HEP

Jon Butterworth, Sabine Kraml, Harrison Prosper +145

Data from particle physics experiments are unique and are often the result of a very large investment of resources. Given the potential scientific impact of these data, which goes…
