Introduction to the PanScales framework, version 0.1

Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +11

In this article, we document version 0.1 of the PanScales code for parton shower simulations. With the help of a few examples, we discuss basic usage of the code, including tests o…

Z and Higgs boson decays with doubly-charged scalars at one-loop: current constraints, future sensitivities, and application to lepton-triality models

Gabriela Lichtenstein, Michael A. Schmidt, German Valencia +1

We analyse the and Higgs boson decays (), and that are induced at one-loop level in models with a doubly-charged isosin…

Axion sourcing in dense stellar matter via CP-violating couplings

Filippo Anzuini, Antonio Gómez-Bañón, José A. Pons +2

Compact objects such as neutron stars and white dwarfs can source axion-like particles and QCD axions due to CP-violating axion-fermion couplings. The magnitude of the axion field…

Complementarity of TRISTAN and Belle II in searches for charged-lepton flavour violation

Gabriela Lichtenstein, Michael A. Schmidt, German Valencia +1

We analyse the potential of the proposed and collider TRISTAN to complement the searches for charged-lepton flavour-violation (CLFV) that can be carried out…

Can supercooled phase transitions explain the gravitational wave background observed by pulsar timing arrays?

Peter Athron, Andrew Fowlie, Chih-Ting Lu +4

Several pulsar timing array collaborations recently reported evidence of a stochastic gravitational wave background (SGWB) at nHz frequencies. Whilst the SGWB could originate from…

A novel unbinned model-independent method to measure the CKM angle in decays with optimised precision

Jake Lane, Evelina Gersabeck, Jonas Rademacker

We present a novel unbinned method to combine and charm threshold data for the amplitude-model unbiased measurement of the CKM angle gamma in cases where the…
