    Jets from Jets: Re-clustering as a tool for large radius jet reconstruction and grooming at the LHC

    Full text link
    Jets with a large radius R≳1R\gtrsim 1 and grooming algorithms are widely used to fully capture the decay products of boosted heavy particles at the Large Hadron Collider (LHC). Unlike most discriminating variables used in such studies, the jet radius is usually not optimized for specific physics scenarios. This is because every jet configuration must be calibrated, insitu, to account for detector response and other experimental effects. One solution to enhance the availability of large-RR jet configurations used by the LHC experiments is {\it jet re-clustering}. Jet re-clustering introduces an intermediate scale r<Rr<R at which jets are calibrated and used as the inputs to reconstruct large radius jets. In this paper we systematically study and propose new jet re-clustering configurations and show that re-clustered large radius jets have essentially the same jet mass performance as large radius groomed jets. Jet re-clustering has the benefit that no additional large-R calibration is necessary, allowing the re-clustered large radius parameter to be optimized in the context of specific precision measurements or searches for new physics

    Declarative vs. procedural rules for religious controversy Is Leibniz's rational approach to heresy an example of procedural rationality?

    I propose to employ the conceptual contrast between procedural knowledge and declarative knowledge instead of the contrast stressed by Marcelo Dascal (2001, 2005) between soft and hard rationality in Leibniz's thought. I propose to examine the interplay between declarative and procedural knowledge in Leibniz's religious thought, and in particular Leibniz's approach to heresy
