# Recent Publications

### Strong first-order phase transitions in the NMSSM — a comprehensive survey

Motivated by the fact that the Next-to-Minimal Supersymmetric Standard Model is one of the most plausible models that can accommodate …

### Bayesian and frequentist approaches to resonance searches

We investigate Bayesian and frequentist approaches to resonance searches using a toy model based on an ATLAS search for the Higgs boson …

### BubbleProfiler: finding the field profile and action for cosmological phase transitions

We present BubbleProfiler, a C++ software package for finding field profiles in bubble walls and calculating the bounce action during …

### Non-parametric uncertainties in the dark matter velocity distribution

We investigate the impact of uncertainty in the velocity distribution of dark matter on direct detection experiments. We construct an …

### Combined collider constraints on neutralinos and charginos

Searches for supersymmetric electroweakinos have entered a crucial phase, as the integrated luminosity of the Large Hadron Collider is …

### Global analyses of Higgs portal singlet dark matter models using GAMBIT

We present global analyses of effective Higgs portal dark matter models in the frequentist and Bayesian statistical frameworks. …

### A fast C++ implementation of thermal functions

We provide a small C++ library with Mathematica and Python interfaces for computing thermal functions, defined  J_\text{B/F}(y^2) …

### DAMPE squib? Significance of the 1.4 TeV DAMPE excess

We present a Bayesian and frequentist analysis of the DAMPE charged cosmic ray spectrum. The spectrum, by eye, contained a spectral …

### Model-independent analysis of the DAMPE excess

The Dark Matter Particle Explorer (DAMPE) recently released measurements of the electron spectrum with a hint of a narrow peak at about …
