Broadband Multi-wavelength Properties of M87 during the 2018 EHT Campaign including a Very High Energy Flaring Episode / Event Horizon Telescope Multi-wavelength Science Collaboration
The nearby elliptical galaxy M87 contains one of the only two supermassive black holes whose emission surrounding the event horizon has been imaged by the Event Horizon Telescope (EHT). [...]

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. [...]

Search for Leptonic CP Violation with the ESSnuSBplus Project / ESSnuSB Collaboration
ESSνSB is a design study for a next-generation long-baseline neutrino experiment that aims at the precise measurement of the CP-violating phase, δCP, in the leptonic sector at the second oscillation maximum. The conceptual design report published from the first phase of the project showed that after 10 years of data taking, more than 70% of the possible δCP range will be covered with 5σ C.L. [...]

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. [...]

Gravitational waves from first-order phase transitions in LISA: reconstruction pipeline and physics interpretation / Caprini, Chiara (Geneva U., Dept. Theor. Phys. ; CERN) ; Jinno, Ryusuke (Tokyo U., RESCEU) ; Lewicki, Marek (Warsaw U.) ; Madge, Eric (Weizmann Inst.) ; Merchand, Marco (Royal Inst.

Phys.) ; Vaskonen, Ville (INFN, Padua ; INFN, Italy ; Unlisted, EE) /LISA Cosmology Working Group
We develop a tool for the analysis of stochastic gravitational wave backgrounds from cosmological first-order phase transitions with LISA: we initiate a template databank for these signals, prototype their searches, and forecast their reconstruction. The templates encompass the gravitational wave signals sourced by bubble collisions, sound waves and turbulence. [...]

Study of nonstandard interactions mediated by a scalar field at the ESSnuSB experiment / ESSnuSB Collaboration
In this paper we study non-standard interactions mediated by a scalar field (SNSI) in the context of ESSnuSB experiment. In particular we study the capability of ESSnuSB to put bounds on the SNSI parameters and also study the impact of SNSI in the measurement of the leptonic CP phase $\delta_{\rm CP}$. [...]

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 ESSnuSB design study: overview and future prospects / ESSnuSB Collaboration
ESSnuSB is a design study for an experiment to measure the CP violation in the leptonic sector at the second neutrino oscillation maximum using a neutrino beam driven by the uniquely powerful ESS linear accelerator. The reduced impact of systematic errors on sensitivity at the second maximum allows for a very precise measurement of the CP violating parameter. [...]
