“…As a consequence for Standard Model processes a similar level of automation as for leadingorder calculations is within reach [34][35][36][37][38][39][40][41][42][43]. An approach applicable for general New Physics extensions, though limited to 2 → 2 processes, has been presented in [44,45].…”

Jet emission at hadron colliders follows simple scaling patterns. Based on perturbative QCD we derive Poisson and staircase scaling for final state as well as initial state radiation. Parton density effects enhance staircase scaling at low multiplicities. We propose experimental tests of our theoretical findings in Z+jets and QCD gap jets production, based on minor additions to current LHC analyses.

“…However, their production cross sections are considerably smaller and are not yet accessible at the LHC, so that we leave the corresponding theoretical update for future work. The semiweak associated production of gauginos with squarks [24,25] and gluinos [26][27][28], which may well become important should the energy available at the LHC prove insufficient for the pair production of the latter, has so far been computed only up to NLO.…”

Motivated by hints for a light Standard Model-like Higgs boson and a shift in experimental attention towards electroweak supersymmetry particle production at the CERN LHC, we update in this paper our precision predictions at next-to-leading order of perturbative QCD matched to resummation at the next-to-leading logarithmic accuracy for direct gaugino pair production in proton-proton collisions with a center-of-mass energy of 8 TeV. Tables of total cross sections are presented together with the corresponding scale and parton density uncertainties for benchmark points adopted recently by the experimental collaborations, and figures are presented for up-to-date model lines attached to them. Since the experimental analyses are currently obtained with parton showers matched to multi-parton matrix elements, we also analyze the precision of this procedure by comparing invariant-mass and transverse-momentum distributions obtained in this way to those obtained with threshold and transverse-momentum resummation.

“…Along these lines, a set of novel predictions for genuine new physics processes we have recently made available, including i) the associated production of squarks and EW gauginos in the MSSM [1]; ii) the production of scalar color-octet (sgluon) pairs [2]; and iii) the different squark and gluino pairwise channels [3]. All these qualify as pioneering examples of fully automated BSM calculations, and expand in many ways the possibilities at reach for the state-of-the-art (modeldependent, hard-coded) NLO packages.…”

“…In timely response to this imperative request, we present the package MADGOLEM [1,2,3,4], by which we completely automate the calculation of NLO cross sections and distributions for 2 → 2 processes within generic beyond-the-Standard-Model (BSM) scenarios. The code is conceived as an independent, modular-structured add-on to MADGRAPH [5], and can thus benefit from its user interfaces, multiple operation possibilities and complementary analysis tools.…”

TeV-scale new physics is already at the spotlight of the current experimental LHC program. In this context, particle phenomenologists are urged to develop automated tools aiming at fast, flexible and accurate theoretical predictions for the major new physics discovery channels. In this contribution we provide a summarized description of the MADGOLEM package, a fully automated tool that enables to evaluate next-to-leading order (NLO) cross sections and distributions for generic heavy particle pair production beyond the Standard Model (BSM). We concisely portray the structure and inner architecture of the code, with our main emphasis on the strategies by which we handle the genuine building blocks of a NLO calculation -the evaluation of the one-loop amplitudes, the renormalization of the ultraviolet singularities, and the subtraction of infrared and on-shell divergences. We discuss the performance of the tool, its multiple functionalities and analysis options, and the attentive cross-checks of all these features. Finally, we present some sample applications to BSM heavy particle production at the LHC.
