Unifying dark matter, dark energy and inflation with a fuzzy dark fluid / Arbey, A. ; Coupechoux, J.-F.
Scalar fields appear in many cosmological models, in particular in order to provide explanations for dark energy and inflation, but also to emulate dark matter. [...]

Relativistic nuclear collisions: Establishing the non-critical baseline for fluctuation measurements / Braun-Munzinger, Peter ; Friman, Bengt ; Redlich, Krzysztof ; Rustamov, Anar ; Stachel, Johanna
We study the influence of global baryon number conservation on the non-critical baseline of net baryon cumulants in heavy-ion collisions in a given acceptance, accounting for the asymmetry between the mean-numbers of baryons and antibaryons. [...]

Azimuthal angle for boson-jet production in the back-to-back limit / Chien, Yang-Ting (YITP, Stony Brook ; Stony Brook U.) ; Rahn, Rudi (Nikhef, Amsterdam ; Delta ITP, Amsterdam) ; Schrijnder van Velzen, Solange (Nikhef, Amsterdam ; Delta ITP, Amsterdam) ; Shao, Ding Yu (Stony Brook U. ; Cal State, L.A. ; UCLA, Los Angeles (main)) ; Waalewijn, Wouter J. (Nikhef, Amsterdam ; Delta ITP, Amsterdam) ; Wu, Bin (CERN)
We show for the first time that the azimuthal angle between a vector boson and a jet, when using the Winner-Take-All recombination scheme, can be predicted at high precision in the back-to-back limit in the transverse plane. [...]

Random Statistics of OPE Coefficients and Euclidean Wormholes / Belin, Alexandre (CERN) ; de Boer, Jan (Amsterdam U.)
We propose an ansatz for OPE coefficients in chaotic conformal field theories which generalizes the Eigenstate Thermalization Hypothesis and describes any OPE coefficient involving heavy operators as a random variable with a Gaussian distribution. [...]

The role of boundary conditions in quantum computations of scattering observables / Briceño, Raúl A. (Jefferson Lab ; Old Dominion U.) ; Guerrero, Juan V. (Jefferson Lab ; Old Dominion U.) ; Hansen, Maxwell T. (CERN) ; Sturzu, Alexandru (New Coll. of Florida)
Quantum computing may offer the opportunity to simulate strongly-interacting field theories, such as quantum chromodynamics, with physical time evolution. [...]

Stellar Signatures of Inhomogeneous Big Bang Nucleosynthesis / Arbey, Alexandre (IP2I, Lyon ; CERN ; IUF, Paris) ; Auffinger, Jérémy (IP2I, Lyon) ; Silk, Joseph (Paris, Inst. Astrophys. ; Johns Hopkins U. ; Oxford U.)
We evaluate abundance anomalies generated in patches of the universe where the baryon-to-photon ratio was locally enhanced by possibly many orders of magnitude in the range $\eta = 10^{-10} - 10^{-1}$. Our study is motivated by the possible survival of rare dense regions in the early universe, the most extreme of which, above a critical threshold, collapsed to form primordial black holes. [...]

Machine Learning and Algebraic Approaches towards Complete Matter Spectra in 4d F-theory / Bies, Martin ; Cvetic, Mirjam ; Donagi, Ron ; Lin, Ling ; Liu, Muyang ; Ruehle, Fabian
Motivated by engineering vector-like (Higgs) pairs in the spectrum of 4d F-theory compactifications, we combine machine learning and algebraic geometry techniques to analyze line bundle cohomologies on families of holomorphic curves. [...]
