New constraints on radiative seesaw models from IceCube and other neutrino detectors
In the case of scalar DM, the absence of a spin dependent scattering on nuclei results in a low capture rate in the Sun, which is reflected in an event rate of less than one per year in the current IceCube configuration with 86 strings.

Precise predictions for electroweak $t\bar t$ production at the LHC in models with flavour non-diagonal $Z'$ boson couplings and $W'$ bosons
We report on our re-calculation of electroweak top-quark pair production in Standard Model extensions with extra heavy neutral and charged spin-1 particles at the LHC with substantial improvements.

How large is the diffractive contribution to inclusive dijet photoproduction in UPCs at the LHC?
Using next-to-leading order (NLO) perturbative QCD, we calculate the diffractive contribution to inclusive dijet photoproduction in Pb-Pb ultraperipheral collisions (UPCs) at the LHC and find that it does not exceed $5-10$% in small-$x_A$ bins in the ATLAS kinematics at $\sqrt{s_{NN}}=5. 02$ TeV.

nCTEQ15HIX -- Extending nPDF Analyses into the High-$x$, Low $Q^2$ Region
We use the nCTEQ analysis framework to investigate nuclear Parton Distribution Functions (nPDFs) in the region of large x and intermediate-to-low $Q$, with special attention to recent JLab Deep Inelastic Scattering data on nuclear targets.

Impact of scale, nuclear PDF and temperature variations on the interpretation of medium-modified jet production data from the LHC
In this paper we present a study of in-medium jet modifications performed with JEWEL and PYTHIA 6. 4, focusing on the uncertainties related to variations of the perturbative scales and nuclear parton distribution functions (PDFs) and on the impact of the initial and crossover temperature variations of the medium.
