An event generator for neutrino-induced Deep Inelastic Scattering and applications to neutrino astronomy
/ Ferrario Ravasio, Silvia (CERN) ; Gauld, Rhorry (Garching, Max Planck Inst.) ; Jäger, Barbara (Tubingen U.) ; Karlberg, Alexander (CERN) ; Zanderighi, Giulia (Garching, Max Planck Inst. ; Munich, Tech. U.)
We extend the recently presented, fully exclusive, next-to-leading-order accurate event generator for the simulation of massless neutral- and charged-current deep inelastic scattering (DIS) to the case of incoming neutrinos. [...]

Towards the super Yang-Mills spectrum at large $N_c$
/ Martins, Sofie (Odense U.) ; Della Morte, Michele (Odense U.) ; Jäger, Benjamin (Odense U.) ; Tsang, Justus Tobias (CERN) ; Ziegler, Felix Paul Gerhard (Edinburgh U.)
We examine one-flavour $SU(N_c)$ gauge theories, where $N_c$ denotes the number of colors, with one fermion in the antisymmetric representation as a candidate to approximate $\mathcal{N}=1$ super Yang Mills due to their equivalence in the large-$N_c$ limit. Summarising results on spectral evaluations of $N_c=3$, we will report on the progress of dynamical calculations for $N_c>3$. [...]

Spectrum of QCD with one flavor: A window for supersymmetric dynamics
/ Della Morte, Michele (Southern Denmark U., CP3-Origins) ; Jäger, Benjamin (Southern Denmark U., CP3-Origins ; U. Southern Denmark, Odense, DIAS) ; Sannino, Francesco (Southern Denmark U., CP3-Origins ; U. Southern Denmark, Odense, DIAS ; Naples U.) ; Tsang, Justus Tobias (CERN ; Southern Denmark U., CP3-Origins) ; Ziegler, Felix P.G. (Edinburgh U.)
We compute the spectrum of the low-lying mesonic states with vector, scalar and pseudoscalar quantum numbers in QCD with one flavour. With three colours the fundamental and the two-index anti-symmetric representations of the gauge group coincide. [...]

Taylor expansion and the Cauchy Residue Theorem for finite-density QCD
/ de Forcrand, Philippe (Zurich, ETH ; CERN) ; Jäger, Benjamin (Southern Denmark U., CP3-Origins ; U. Southern Denmark, Odense, DIAS)
We present an update on our efforts to determine the Taylor coefficients of the $\mu/T$ expansion of the pressure for finite-density QCD. Here, we explore alternatives based on the Cauchy Residue Theorem, which allows us to use a discretized contour to determine the desired spectral moments occurring in the Taylor expansion of QCD at zero chemical potential..

Precise predictions for same-sign W-boson scattering at the LHC
/ Ballestrero, Alessandro (INFN, Turin) ; Biedermann, Benedikt (Wurzburg U.) ; Brass, Simon (Siegen U.) ; Denner, Ansgar (Wurzburg U.) ; Dittmaier, Stefan (Freiburg U.) ; Frederix, Rikkert (Munich, Tech. U.) ; Govoni, Pietro (INFN, Milan Bicocca ; Milan U.) ; Grossi, Michele (Pavia U. ; INFN, Pavia) ; Jäger, Barbara (Tubingen U.) ; Karlberg, Alexander (Zurich U.) et al.
Vector-boson scattering processes are of great importance for the current run-II and future runs of the Large Hadron Collider. The presence of triple and quartic gauge couplings in the process gives access to the gauge sector of the Standard Model (SM) and possible new-physics contributions there. [...]

Vector boson scattering: Recent experimental and theory developments
/ Anders, C.F. (Heidelberg U.) ; Alessandro, Ballestrero (INFN, Turin) ; Balz, J. (Mainz U.) ; Bellan, R. (INFN, Turin ; Turin U.) ; Biedermann, B. (U. Wurzburg (main)) ; Bittrich, C. (Dresden, Tech. U.) ; Braß, S. (Siegen U.) ; Brivio, I. (Bohr Inst.) ; Bruni, L.S. (Nikhef, Amsterdam) ; Butterworth, J. (University Coll. London) et al.
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..

Alternatives to the stochastic "noise vector" approach
/ de Forcrand, Philippe (CERN ; Zurich, ETH) ; Jäger, Benjamin (Zurich, ETH ; Odense U. ; Southern Denmark U., CP3-Origins)
Several important observables, like the quark condensate and the Taylor coefficients of the expansion of the QCD pressure with respect to the chemical potential, are based on the trace of the inverse Dirac operator and of its powers. Such traces are traditionally estimated with "noise vectors" sandwiching the operator. [...]
