ColoRea: Colour Rearrangement for Dipole Showers

In this talk I presented an algorithm to correct for wrong assignment of colour dipoles in the cascade of dipole showers. It is explained how simple matrix elements can be used to reorder the colour connections for the evolution of the following cascade. I discuss the possibility to modify the splitting kernels to include an improved behaviour. Further a numerical study is presented that indicates

Merging NLO Multi-jet Calculations with Improved Unitarization

We present an algorithm to combine multiple matrix elements at LO and NLO with a parton shower. We build on the unitarized merging paradigm. The inclusion of higher orders and multiplicities reduce the scale uncertainties for observables sensitive to hard emissions, while preserving the features of inclusive quantities. The combination allows further soft and collinear emissions to be predicted by

Parton Shower Uncertainties with Herwig 7: Benchmarks at Leading Order

We perform a detailed study of the sources of perturbative uncertainty in parton-shower predictions within the Herwig 7 event generator. We benchmark two rather different parton-shower algorithms, based on angular-ordered and dipole-type evolution, against each other. We deliberately choose leading order plus parton shower as the benchmark setting to identify a controllable set of uncertainties. T

The Limits of Free Will : Selected Essays

This volume contains a selection of chapters concerning free will and moral responsibility. The problems arising in this field of philosophy, which are deeply rooted in the history of the subject, are also intimately related to a wide range of other fields, such as law and criminology, moral psychology, theology, and, more recently, neuroscience. The chapters included in this collection were writt

Δ9-Tetrahydrocannabinol and Cannabinol Activate Capsaicin-Sensitive Sensory Nerves via a CB1 and CB2 Cannabinoid Receptor-Independent Mechanism

Although Δ9-tetrahydrocannabinol (THC) produces analgesia, its effects on nociceptive primary afferents are unknown. These neurons participate not only in pain signaling but also in the local response to tissue injury. Here, we show that THC and cannabinol induce a CB1/CB 2 cannabinoid receptor-independent release of calcitonin gene-related peptide from capsaicin-sensitive perivascular sensory ner
