NLO + parton-shower generator for Wc production in the POWHEG BOX RES / Ferrario Ravasio, Silvia (CERN) ; Oleari, Carlo (Milan Bicocca U. ; INFN, Milan Bicocca)
We present the implementation of a next-to-leading-order plus parton-shower event generator for the hadronic production of a heavy charm quark accompanied by a leptonically-decaying $W$ boson in the POWHEG BOX RES framework. We consider both signatures, i.e. [...]

Monte Carlo event generators (MCEGs) are the indispensable workhorses of particle physics, bridging the gap between theoretical ideas and first-principles calculations on the one hand, and the complex detector signatures and data of the experimental community on the other hand. [...]

All-orders behaviour and renormalons in top-mass observables / Ferrario Ravasio, Silvia (Milan Bicocca U. ; INFN, Milan Bicocca) ; Nason, Paolo (CERN ; INFN, Milan Bicocca) ; Oleari, Carlo (INFN, Milan Bicocca ; Milan Bicocca U.)
We study a simplified model of top production and decay, consisting in a virtual vector boson $W^*$ decaying into a massive-massless $t$-$\bar{b}$ quark-antiquark pair. The top has a finite width and further decays into a stable vector boson $W$ and a $b$ quark. [...]

This document summarises the talks and discussions happened during the VBSCan Split17 workshop, the first general meeting of the VBSCan COST Action network. This collaboration is aiming at a consistent and coordinated study of vector-boson scattering from the phenomenological and experimental point of view, for the best exploitation of the data that will be delivered by existing and future particle colliders..

A Theoretical Study of Top-Mass Measurements at the LHC Using NLO+PS Generators of Increasing Accuracy / Ferrario Ravasio, Silvia (INFN, Milan Bicocca ; Milan Bicocca U.) ; Ježo, Tomáš (Zurich U.) ; Nason, Paolo (CERN ; INFN, Milan Bicocca) ; Oleari, Carlo (INFN, Milan Bicocca ; Milan Bicocca U.)
In this paper we study the theoretical uncertainties in the determination of the top-quark mass using next-to-leading-order (NLO) generators interfaced to parton showers (PS) that have different levels of accuracy. Specifically we consider three generators: one that implements NLO corrections in the production dynamics, one that includes also NLO corrections in top decay in the narrow width approximation, and one that implements NLO corrections for both production and decay including finite-width and interference effects. [...]

Merging H/W/Z + 0 and 1 jet at NLO with no merging scale: a path to parton shower + NNLO matching / Hamilton, Keith (CERN) ; Nason, Paolo (INFN, Milan Bicocca) ; Oleari, Carlo (INFN, Milan Bicocca ; Milan Bicocca U.) ; Zanderighi, Giulia (Oxford U.)
We consider the POWHEG generator for a H/W/Z boson plus one jet, augmented with the recently proposed MiNLO method for the choice of scales and the inclusion of Sudakov form factors. Within this framework, the generator covers all the transverse-momentum region of the H/W/Z boson, i.e. [...]

NLO Higgs boson production plus one and two jets using the POWHEG BOX, MadGraph4 and MCFM / Campbell, John M.

We present a next-to-leading order calculation of Higgs boson production plus one and two jets via gluon fusion interfaced to shower Monte Carlo programs, implemented according to the POWHEG method. For this implementation we have used a new interface of the POWHEG BOX with MadGraph4, that generates the codes for generic Born and real processes automatically. [...]

Sudakov Resummation Effects in Prompt-Photon Hadroproduction / Catani, Stefano (CERN) ; Mangano, Michelangelo L. (CERN) ; Nason, Paolo (INFN, Milan) ; Oleari, Carlo (Durham U.) ; Vogelsang, Werner (SUNY, Stony Brook)
We compute the effects of soft-gluon resummation, at the next-to-leading-logarithmic level, in the fixed-target hadroproduction cross section for prompt photons. We find in general that the corrections to the fixed next-to-leading-order results are large for large renormalization scales, and small for small scales. [...]

A Fixed-Order Calculation of the Heavy-Quark Fragmentation Function in $e^{+}e^{-}$ Collisions / Nason, Paolo (CERN) ; Oleari, Carlo (Durham U.)
We use a recently completed O(alpha_s^2) fixed-order calculation of the heavy-flavour production cross section in e+e- collisions to compute the heavy-quark fragmentation function. We fit the result of our calculation, convoluted with a Peterson fragmentation function, to available data for charm production, and thus obtain a value for the parameter epsilon in the Peterson function.

On the Fragmentation Function for Heavy Quarks in $e^{+}e^{-}$ collisions / Nason, Paolo (CERN) ; Oleari, Carlo (Milan U. ; INFN, Milan)
We use a recent O(alpha_s^2) calculation of the differential cross section for the production of heavy quarks in e+e- annihilation to compute a few moments of the heavy quark single-inclusive production cross section. We verify that, contrary to some recent claims, the leading and next-to-leading logarithmic terms in this cross section are correctly given by the standard NLO fragmentation function formalism for heavy quark production..
