High-precision search for dark photon dark matter with the Parkes Pulsar Timing Array

Xiao Xue, Zi-Qing Xia, Xingjiang Zhu +20

The nature of dark matter remains obscure in spite of decades of experimental efforts. The mass of dark matter candidates can span a wide range, and its coupling with the Standard…

Likelihood analysis of the flavour anomalies and in the general two Higgs doublet model

Peter Athron, Csaba Balazs, Tomás E. Gonzalo +3

We present a likelihood analysis of the general two Higgs doublet model, using the most important currently measured flavour observables, in view of the anomalies in charged curren…

HEJ 2.1: High-energy Resummation with Vector Bosons and Next-to-Leading Logarithms

Jeppe R. Andersen, James Black, Helen Brooks +4

We present version 2.1 of the High Energy Jets (HEJ) event generator for hadron colliders. HEJ is a Monte Carlo generator for processes at high energies with multiple well-separate…

Two-loop Prediction of the Anomalous Magnetic Moment of the Muon in the Two-Higgs Doublet Model with GM2Calc 2

Peter Athron, Csaba Balazs, Adriano Cherchiglia +4

We present an extension of the GM2Calc software to calculate the muon anomalous magnetic moment () in the Two-Higgs Doublet Model. The Two-Higgs Doublet Model is…

On long-lived electroweak-singlet coloured scalars

Christian T Preuss, German Valencia

There has been much recent interest in long-lived massive particles at the LHC, understood as those with lifetimes between tens of micrometers and several meters. In this context w…

Towards NNLO+PS Matching with Sector Showers

John M Campbell, Stefan Höche, Hai Tao Li +2

We outline a new technique for the fully-differential matching of final-state parton showers to NNLO calculations, focussing here on the simplest case of leptonic collisions with t…
