Heavy-to-light form factors to three loops
/ Fael, Matteo (CERN) ; Huber, Tobias (Siegen U.) ; Lange, Fabian (Zurich U. ; PSI, Villigen) ; Müller, Jakob (Siegen U.) ; Schönwald, Kay (Zurich U.) ; Steinhauser, Matthias (KIT, Karlsruhe, TTP)
We compute three-loop corrections of $\mathcal{O}(\alpha_{s}^3)$ to form factors with one massive and one massless quark coupling to an external vector, axialvector, scalar, pseudoscalar, or tensor current. [...]

Laboratory realization of relativistic pair-plasma beams
/ Arrowsmith, C.D. (Oxford U.) ; Simon, P. (CERN ; Darmstadt, GSI) ; Bilbao, P. (Lisbon, IST) ; Bott, A.F.A. (Oxford U.) ; Burger, S. (CERN) ; Chen, H. (LLNL, Livermore) ; Cruz, F.D. (Lisbon, IST) ; Davenne, T. (Rutherford) ; Efthymiopoulos, I. (CERN) ; Froula, D.H. (Rochester U.) et al.
Relativistic electron-positron plasmas are ubiquitous in extreme astrophysical environments such as black holes and neutron star magnetospheres, where accretion-powered jets and pulsar winds are expected to be enriched with such pair plasmas. [...]

Causality Bounds on Dissipative General-Relativistic Magnetohydrodynamics

We determine necessary and sufficient conditions under which a large class of relativistic generalizations of Braginskii's magnetohydrodynamics, described using Israel-Stewart theory, are causal and strongly hyperbolic in the fully nonlinear regime in curved spacetime. [...]
