A global fit of the MSSM with GAMBIT / GAMBIT Collaboration
We study the seven-dimensional Minimal Supersymmetric Standard Model (MSSM7) with the new GAMBIT software framework, with all parameters defined at the weak scale. Our analysis significantly extends previous weak-scale, phenomenological MSSM fits, by adding more and newer experimental analyses, improving the accuracy and detail of theoretical predictions, including dominant uncertainties from the Standard Model, the Galactic dark matter halo and the quark content of the nucleon, and employing novel and highly-efficient statistical sampling methods to scan the parameter space.

Global fits of GUT-scale SUSY models with GAMBIT / GAMBIT Collaboration
We present the most comprehensive global fits to date of three supersymmetric models motivated by grand unification: the Constrained Minimal Supersymmetric Standard Model (CMSSM), and its Non-Universal Higgs Mass generalisations NUHM1 and NUHM2. We include likelihoods from a number of direct and indirect dark matter searches, a large collection of electroweak precision and flavour observables, direct searches for supersymmetry at LEP and Runs I and II of the LHC, and constraints from Higgs observables.

Status of the scalar singlet dark matter model / GAMBIT Collaboration
One of the simplest viable models for dark matter is an additional neutral scalar, stabilised by a $\mathbb{Z}_2$ symmetry. Using the GAMBIT package and combining results from four independent samplers, we present Bayesian and frequentist global fits of this model. [...]

GAMBIT: The Global and Modular Beyond-the-Standard-Model Inference Tool / GAMBIT Collaboration
We describe the open-source global fitting package GAMBIT: the Global And Modular Beyond-the-Standard-Model Inference Tool. GAMBIT combines extensive calculations of observables and likelihoods in particle and astroparticle physics with a hierarchical model database, advanced tools for automatically building analyses of essentially any model, a flexible and powerful system for interfacing to external codes, a suite of different statistical methods and parameter scanning algorithms, and a host of other utilities designed to make scans faster, safer and more easily-extendible than in the past.

Thermal WIMPs and the Scale of New Physics: Global Fits of Dirac Dark Matter Effective Field Theories / GAMBIT Collaboration
We assess the status of a wide class of WIMP dark matter (DM) models in light of the latest experimental results using the global fitting framework $\textsf{GAMBIT}$. We perform a global analysis of effective field theory (EFT) operators describing the interactions between a gauge-singlet Dirac fermion and the Standard Model quarks, the gluons and the photon.

Decoherence in Neutrino Oscillation at the ESSnuSB Experiment / ESSnuSB Collaboration
Neutrino oscillation experiments provide a unique window in exploring several new physics scenarios beyond the standard three flavour. One such scenario is quantum decoherence in neutrino oscillation which tends to destroy the interference pattern of neutrinos reaching the far detector from the source. [...]

Exploring atmospheric neutrino oscillations at ESSnuSB / ESSnuSB Collaboration
This study provides an analysis of atmospheric neutrino oscillations at the ESSnuSB far detector facility. The prospects of the two cylindrical Water Cherenkov detectors with a total fiducial mass of 540 kt are investigated over 10 years of data taking in the standard three-flavor oscillation scenario.

Phases of Pseudo-Nambu-Goldstone Bosons / Koutroulis, Fotis (Warsaw U.) ; McCullough, Matthew (CERN) ; Merchand, Marco (Warsaw U. ; Royal Inst. Tech., Stockholm ; Stockholm U., OKC) ; Pokorski, Stefan (Warsaw U.) ; Sakurai, Kazuki (Warsaw U.)
We study the vacuum dynamics of pseudo-Nambu-Goldstone bosons (pNGBs) for $SO(N+1) \rightarrow SO(N)$ spontaneous and explicit symmetry breaking. We determine the magnitude of explicit symmetry breaking consistent with an EFT description of the effective potential at zero and finite temperatures. [...]

The European Spallation Source neutrino super-beam conceptual design report / Alekou, A. (CERN ; Uppsala U.) ; Baussan, E. (Strasbourg, IPHC) ; Bhattacharyya, A.K. (ESS, Lund) ; Blaskovic Kraljevic, N. (ESS, Lund) ; Blennow, M. (Royal Inst. Tech., Stockholm ; Stockholm U., OKC) ; Bogomilov, M. (Sofiya U.) ; Bolling, B. (ESS, Lund) ; Bouquerel, E. (Strasbourg, IPHC) ; Buchan, O. (ESS, Lund) ; Burgman, A. (Lund U.) et al.
This conceptual design report provides a detailed account of the European Spallation Source neutrino Super Beam (ESS$\nu$SB) feasibility study. This facility has been proposed after the measurements reported in 2012 of a relatively large value of the neutrino mixing angle $\theta_{13}$, which raised the possibility of observing potential CP violation in the leptonic sector with conventional neutrino beams.
