Euclid I. Overview of the Euclid mission

Jean-Paul Richard Kneib, Frédéric Courbin, Georges Meylan, Pascale Jablonka, Michaela Hirschmann, Yves Revaz, Austin Chandler Peel, Lucie Anemone Scharré, Bastien Clément

The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Euclid is a medium-class mission in the Cosmic Vision 2015–2025 programme of the ...

Comparing Compressed and Full-Modeling analyses with FOLPS: implications for DESI 2024 and beyond

Antoine Philippe Jacques Rocher

The Dark Energy Spectroscopic Instrument (DESI) will provide unprecedented information about the large-scale structure of our Universe. In this work, we study the robustness of the theoretical modelling of the power spectrum of FOLPS, a novel effective fie ...

Observation of an Axial-vector State in the Study of the Decay Ψ(3686) → Φηη'

Yunxuan Song

Using (2712.4 +/- 14.3) x 10(6) psi(3686) events collected with the BESIII detector at BEPCII, a partial wave analysis of the decay psi(3686) ->phi eta eta' is performed with the covariant tensor approach. In addition to the established states h(1)(1900) a ...

A comparison of effective field theory models of redshift space galaxy power spectra for DESI 2024 and future surveys

Antoine Philippe Jacques Rocher

In preparation for the next generation of galaxy redshift surveys, and in particular the year-one data release from the Dark Energy Spectroscopic Instrument (DESI), we investigate the consistency of a variety of effective field theory models that describe ...

Euclid V. The Flagship galaxy mock catalogue: A comprehensive simulation for the Euclid mission

Frédéric Courbin, Georges Meylan

We present the Flagship galaxy mock, a simulated catalogue of billions of galaxies designed to support the scientific exploitation of the Euclid mission. Euclid is a medium-class mission of the European Space Agency optimised to determine the properties of ...

The stringy S-matrix bootstrap: maximal spin and superpolynomial softness

Kelian Philippe Häring

We explore the space of meromorphic amplitudes with extra constraints coming from the shape of the leading Regge trajectory. This information comes in two guises: it bounds the maximal spin of exchanged particles of a given mass; it leads to sum rules obey ...

Euclid preparation: XLII. A unified catalogue-level reanalysis of weak lensing by galaxy clusters in five imaging surveys

Frédéric Courbin, Georges Meylan, Austin Chandler Peel

Precise and accurate mass calibration is required to exploit galaxy clusters as astrophysical and cosmological probes in the Euclid era. Systematic errors in lensing signals by galaxy clusters can be empirically estimated by comparing different surveys wit ...

Strong and Weak CP Tests in Sequential Decays of Polarized Σ0 Hyperons

Yunxuan Song

The J/psi,psi(3686) -> Sigma(0)(Sigma) over bar (0) processes and subsequent decays are studied using the world's largest J/psi and psi(3686) data samples collected with the BESIII detector. The parity-violating decay parameters of the decays Sigma(0) -> L ...

SLAP: Succinct Lattice-Based Polynomial Commitments from Standard Assumptions

Giacomo Fenzi

Recent works on lattice-based extractable polynomial commitments can be grouped into two classes: (i) non-interactive constructions that stem from the functional commitment by Albrecht, Cini, Lai, Malavolta and Thyagarajan (CRYPTO 2022), and (ii) lattice a ...

Cosmic evolution of the Faraday rotation measure in the intracluster medium of galaxy clusters

Salim Bennouna, Abhijit Bhausaheb Bendre, Yoan Rappaz

Context. Radio observations have revealed magnetic fields in the intracluster medium (ICM) of galaxy clusters, and their energy density is nearly in equipartition with the turbulent kinetic energy. This suggests magnetic field amplification by dynamo proce ...

Electronic excitations and spin interactions in chromium trihalides from embedded many-body wavefunctions

Oleg Yazyev, Ravi Yadav

Although chromium trihalides are widely regarded as a promising class of two-dimensional magnets for next-generation devices, an accurate description of their electronic structure and magnetic interactions has proven challenging to achieve. Here, we quanti ...

The O(N) monolith reloaded: sum rules and Form Factor Bootstrap

Miguel Alexandre Ribeiro Correia, Antoine Vuignier

We revisit the space of gapped quantum field theories with a global O(N) symmetry in two spacetime dimensions. Previous works using S-matrix bootstrap revealed a rich space in which integrable theories such as the non-linear sigma model appear at special p ...

Landmine Detection Using Electromagnetic Time Reversal-Based Methods: 1. Classical TR, Iterative TR, DORT and TR-MUSIC

Farhad Rachidi-Haeri, Marcos Rubinstein, Carlos Alberto Romero Romero, Hamidreza Karami

In this paper, we present a review and classification of the published works on the use of Electromagnetic Time Reversal (EMTR)-based methods to locate landmines. Different approaches for landmine localization using EMTR are investigated. Specifically, the ...
