Nuclear PDFs
K. Greve, T. Ježo, M. Klasen +3
We summarize the current status of global analyses of model-independent nuclear parton distri- bution functions (nPDFs). A carefully conducted global analysis of nPDFs in the era o…
A Powheg generator for - and -channel single-top production and decay including non-resonant effects
Melissa van Beekveld, Robin van Bijleveld, Silvia Ferrario Ravasio +2
We present a next-to-leading order + parton shower generator for - and -channel single-top production in hadron colliders, for a leptonically-decaying top, including off-shel…
Impact of Open Heavy-Flavour Production on nCTEQ Nuclear PDFs
Jan Wissmann, Tomáš Ježo, Michael Klasen +2
We present nCTEQ26OHF, a global analysis of nuclear parton distribution functions (nPDFs) within the nCTEQ framework. In this analysis, constrasting the main nCTEQ26 release, we re…
Determination of Nuclear PDFs using Markov Chain Monte Carlo Methods
N. Derakhshanian, P. Risse, T. Jezo +3
Global QCD analyses of nuclear parton distribution functions (nPDFs) have traditionally relied on the Hessian method for uncertainty estimation. However, the inherent Gaussian appr…

Edoardo Spezzano, Tomas Jezo, Michael Klasen +2
We present next-to-leading-order (NLO) calculations of heavy-quark contributions to deep-inelastic scattering (DIS) structure functions and within the Aivazis--Collins-…
Determination of proton PDF uncertainties with Markov chain Monte Carlo
Peter Risse, Nasim Derakhshanian, Tomas Jezo +2
We present an analysis of parton distribution functions (PDFs) of the proton using Markov Chain Monte Carlo (MCMC) methods. The MCMC approach naturally implements Bayes' theorem an…
Theory uncertainties of the irreducible background to VBF Higgs production
Xuan Chen, Silvia Ferrario Ravasio, Yacine Haddad +7
Higgs boson production through gluon fusion in association with two jets is an irreducible background to Higgs boson production through vector boson fusion, one of the most importa…
Conversion of photons to dileptons in the Kroll-Wada and parton shower approaches
Tomáš Ježo, Michael Klasen, Alexander Puck Neuwirth
The study of dileptons in high-energy heavy-ion collisions provides critical insights into the properties of the quark-gluon plasma and the thermal radiation emitted throughout its…
MATRIX HAWAII: PineAPPL interpolation grids with MATRIX
S. Devoto, T. Jezo, S. Kallweit +1
We present an interface between PineAPPL and Matrix, which allows fully differential cross sections to be calculated in the form of interpolation grids, accurate at next-to-next-to…
Prompt photon production with two jets in POWHEG
Tomáš Ježo, Michael Klasen, Alexander Neuwirth
Prompt photon production is highly sensitive to the distribution of quarks and gluons in free protons and nuclei and an important baseline for phenomenological studies of the prope…
A Markov Chain Monte Carlo determination of Proton PDF uncertainties at NNLO
Peter Risse, Nasim Derakhshanian, Tomas Ježo +2
The current scientific standard in PDF uncertainty estimation relies either on repeated fits over artificially generated data to arrive at Monte Carlo samples of best fits or on th…
PineAPPL Grids of Open Heavy-Flavor Production in the GM-VFNS
Jan Wissmann, Tomáš Ježo, Ingo Schienbein +2
Many next-to-leading order QCD predictions are available through Monte Carlo (MC) simulations. Usually, multiple CPU hours are needed to calculate predictions at a required precisi…
Di-electron production at the LHC: Unravelling virtual-photon and heavy-flavour contributions
Anton Andronic, Tomáš Ježo, Michael Klasen +2
The production of virtual photons is a very sensitive probe of the properties of the quark-gluon plasma. As they are experimentally detected by lepton pairs, they suffer from a lar…

We extend the QCD Parton Model analysis using a factorized nuclear structure model incorporating individual nucleons and pairs of correlated nucleons. Our analysis of high-energy d…
Kicking it Off(-shell) with Direct Diffusion
Anja Butter, Tomas Jezo, Michael Klasen +3
Off-shell effects in large LHC backgrounds are crucial for precision predictions and, at the same time, challenging to simulate. We present a novel method to transform high-dimensi…
Resonance-aware NLOPS matching for off-shell production with semileptonic decays
Tomáš Ježo, Jonas M. Lindert, Stefano Pozzorini
The increasingly high accuracy of top-quark studies at the LHC calls for a theoretical description of production and decay in terms of exact matrix elements for the full…
