Z boson production in proton-lead collisions at the LHC accounting for transverse momenta of initial partons

E. Blanco, A. Van Hameren, Hannes Jung, Alexander Kusina & K. Kutak
We perform a calculation of inclusive $Z$ boson production in proton-lead collisions at the LHC taking into account the transverse momenta of the initial partons. We use the framework of $k_T$-factorization combining transverse momentum dependent parton distributions (TMDs) with off-shell matrix elements. In order to do it we need to construct appropriate TMDs for lead nuclei which is done using the parton branching method. Our computations are compared with data from CMS taken at $\sqrt{s}=5.02$...

Three loop heavy quark form factors and their asymptotic behavior

J. Ablinger, J. Blümlein, P. Marquard, Narayan Rana & C. Schneider
A summary of the calculation of the color-planar and complete light quark contributions to the massive three-loop form factors is presented. Here a novel calculation method for the Feynman integrals is used, solving general uni-variate first order factorizable systems of differential equations. We also present predictions for the asymptotic structure of these form factors.

Production of Z-bosons in the parton branching method

Armando Bermudez Martinez, P. Connor, Daniela Dominguez Damiani, L. I. Estevez Banos, F. Hautmann, Hannes Jung, J. Lidrych, Melanie Viola Schmitz, S. Taheri Monfared, Qun Wang & R. Zlebcik
Transverse Momentum Dependent (TMD) parton distributions obtained from the Parton Branching (PB) method are combined with next-to-leading-order (NLO) calculations of Drell-Yan (DY) production. We apply the MCatNLO method for the hard process calculation and matching with the PB TMDs. We compute predictions for the transverse momentum, rapidity and $\phi^*$ spectra of Z-bosons. We find that the theoretical uncertainties of the predictions are dominated by the renormalization and factorization scale dependence, while the impact of TMD...

Non-thermal emission from the reverse shock of the youngest galactic Supernova remnant G1.9+0.3

R. Brose, I. Sushch, Martin Pohl, K. J. Luken, M. D. Filipovic & R. Lin
Context. The youngest Galactic supernova remnant G1.9+0.3 is an interesting target for next generation gamma-ray observatories. So far, the remnant is only detected in the radio and the X-ray bands, but its young age of ~100 yrs and inferred shock speed of ~14,000 km/s could make it an efficient particle accelerator. Aims. We aim to model the observed radio and X-ray spectra together with the morphology of the remnant. At the same time, we aim...
