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…
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…
Precision predictions for dark matter with DM@NLO in the MSSM
Julia Harz, Björn Herrmann, Michael Klasen +2
We present DM@NLO, a Fortran 77 based program with a C++ interface dedicated to precision calculations of dark matter (DM) (co)annihilation cross-sections and elastic dark matter-n…
Modification of Quark-Gluon Distributions in Nuclei by Correlated Nucleon Pairs
nCTEQ Collaboration, A. W. Denniston, T. Jezo +15
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…
Target mass corrections in lepton--nucleus DIS: theory and applications to nuclear PDFs
R. Ruiz, K. F. Muzakka, C. Leger +14
Motivated by the wide range of kinematics covered by current and planned deep-inelastic scattering (DIS) facilities, we revisit the formalism, practical implementation, and numeric…

We present the full one-loop SUSY-QCD corrections to stop-antistop annihilation into gluons and light quarks within the Minimal Supersymmetric Standard Model including Sommerfeld e…
Compatibility of Neutrino DIS Data and Its Impact on Nuclear Parton Distribution Functions
K. F. Muzakka, P. Duwentäster, T. J. Hobbs +9
In global analyses of nuclear parton distribution functions (nPDFs), neutrino deep-inelastic scattering (DIS) data have been argued to exhibit tensions with the data from charged-l…
Constraining the nuclear gluon PDF with inclusive hadron production data
P. Duwentäster, L. A. Husová, T. Ježo +7
The nuclear parton distribution functions (nPDFs) of gluons are known to be difficult to determine with fits of deep inelastic scattering (DIS) and Drell-Yan (DY) data alone. There…
nCTEQ PDFs at the LHC: Vector boson production in heavy ion collisions
The nCTEQ Collaboration, D. B. Clark, E. Godat +13
Extraction of the strange quark PDF is a long-standing puzzle. We use the nCTEQ nPDFs with uncertainties to study the impact of the LHC W/Z production data on both the flavor diffe…
Direct detection of neutralino dark matter with DM@NLO
M. Klasen, K. Kovarik, S. Schmiemann
We calculate spin-independent and spin-dependent direct detection cross sections of neutralino dark matter at next-to-leading order of QCD. The numerical effects are comparable in…
