Parameter Inference from Event Ensembles and the Top-Quark Mass

Understand

One of the key tasks of any particle collider is measurement.

• In practice, this is often done by fitting data to a simulation, which depends on many parameters.
• Sometimes, when the effects of varying different parameters are highly correlated, a large ensemble of data may be needed to resolve parameter-space degeneracies.
• An important example is measuring the top-quark mass, where other physical and unphysical parameters in the simulation must be marginalized over when fitting the top-quark mass parameter.
