Discovery Sensitivity for a Counting Experiment with Background Uncertainty

Enzo Canonero, Glen Cowan

In Particle Physics, a search for a new signal process is often based on observing a Poisson-distributed number of events, whose mean contains contributions from background and, if…

Correlated Systematic Uncertainties and Errors-on-Errors in Measurement Combinations: Methodology and Application to the 7-8 TeV ATLAS-CMS Top Quark Mass Combination

Enzo Canonero, Glen Cowan

The Gamma Variance Model (GVM) is a statistical model that incorporates uncertainties in the assignment of systematic errors (informally called errors-on-errors). The model is of p…

A search for baryogenesis and dark matter in $B^{+} \to I^_{c}^{+} + invisible$ decays

BABAR Collaboration

A mechanism of baryogenesis and dark matter production via $B$ -meson oscillations and decays has recently been proposed to explain the observed dark matter abundance and matter-ant…
