Geometric Baryogenesis with Chiral-Time Equivalence

Sameer Ahmad Mir, Arshid Shabir, Swatantra Kumar Tiwari +1

The asymmetry between matter and antimatter demands a cause as simple as it is profound. Here we show that a single geometric principle Chiral-Time Equivalence (CTE)-suffices to ge…

Misalignment from kicks: the impact of particle interactions on ultra-light dark matter

Clare Burrage, Sergio Sevillano Muñoz

Oscillating ultra-light scalar fields are a natural explanation for the dark matter in our universe, as long as a mechanism, often called a misalignment mechanism, exists to explai…

Lecture Notes: Probing ultralight axion-like particles with quantum technology

Sreemanti Chakraborti

We review the physics of ultralight axion-like particles (ALPs) as dark matter candidates and the experimental strategies used to search for them with precision and quantum technol…

Lessons from the first JUNO results

Ivan Esteban, M. C. Gonzalez-Garcia, Michele Maltoni +3

First results from the JUNO reactor neutrino experiment already determine with world-leading precision the small neutrino squared-mass splitting $Δ m_{21}^{2}$ and the mixing angle $θ…

Axion superradiance

Francesca Chadha-Day

Light bosonic fields may suffer an instability around a rotating compact object. This process, known as superradiance, leads to the exponential amplification of the field around a…

Analytical results for the C-angularity soft function at NNLO

Alexander Bennett, Emmet P. Byrne, Jonathan R. Gaunt +1

We compute the soft function at NLO and NNLO for a one-parameter family of event shapes we call C-angularity. This family contains C-parameter as a specific choice of the parameter…

Domain Walls in $A_{4}$ Flavour Models

Bowen Fu, Stephen F. King, Luca Marsili +2

The spontaneous breaking of an $A_{4}$ flavour symmetry, often used to predict leptonic mixing, can lead to the formation of domain walls which can annihilate and generate a stochast…

Unified Functional-Holographic Theory of the QCD Critical End Point

Sameer Ahmad Mir, Saeed Uddin, Swatantra Kumar Tiwari +1

We develop a thermodynamically consistent nonperturbative framework for equilibrium QCD criticality, unifying DSE quark propagation, FRG flow, and PNJL thermodynamics for coupled c…

Do neutrinos dream in 5D? Towards a comprehensive extra-dimensional neutrino phenomenology

Arturo de Giorgi, Dhruv Pasari, Jessica Turner

This paper provides a comprehensive overview of neutrino masses and mixing in Large Extra Dimension scenarios, focusing on the phenomenological impact of a five-dimensional (5D) bu…

CP Violation in Charmed Meson Decays into Final States with $η^{'}$

Carolina Bolognani, Ulrich Nierste, Stefan Schacht +1

We derive Standard Model predictions for the CP asymmetries of singly-Cabibbo suppressed $D \to P η^{'}$ decays, where $P = K, π, η$ . Our predictions are based on the approximate SU…

Assessing (H)EFT theory errors by pitting EoM against Field Redefinitions

Rodrigo Alonso, Christoph Englert, Wrishik Naskar +1

Truncations of effective field theory expansions are technically necessary but inherently intertwined with the redundancies of general field redefinitions. This can be viewed as a…

Probing the Phenomenology of Dark Matter from Decoupled Freeze-Out

Geneviève Bélanger, Aoife Bharucha, Sreemanti Chakraborti +2

We consider a model of dark matter where the mediator corresponds to a superposition of a scalar and pseudoscalar, and the scenario where, after reheating, the number densities of…

Global Determination of $∣ V_{u s} ∣$

Matthew Kirk, Danny van Dyk

In light of ongoing issues with the first-row unitarity test of the CKM matrix, we showcase a global fit to measurements of $K \to ℓ ν$ , $K \to π ℓ ν$ , $τ \to K ν$ , and $τ \to K π ν$ …

Symbolic Regression and Differentiable Fits in Beyond the Standard Model Physics

Shehu AbdusSalam, Steven Abel, Deaglan Bartlett +1

We demonstrate the efficacy of symbolic regression (SR) to probe models of particle physics Beyond the Standard Model (BSM), by considering the so-called Constrained Minimal Supers…

Isospin-based EWP-tree Relations

Bhubanjyoti Bhattacharya, Marianne Bouchard, Alexandre Jean +2

In 1998, it was shown that, if flavor SU(3) symmetry [SU(3) $_{F}$ ] is assumed in charmless $B \to P P$ decays ( $P$ is a light pseudoscalar meson), some reduced matrix elements involvi…

Stable and Interpretable Jet Physics with IRC-Safe Equivariant Feature Extraction

Partha Konar, Vishal S. Ngairangbam, Michael Spannowsky +1

Deep learning has achieved remarkable success in jet classification tasks, yet a key challenge remains: understanding what these models learn and how their features relate to known…

nuSTORM as a Precision Probe of the Standard Model and New Physics

Jack Franklin, Rohan Kamath, Dhruv Pasari +3

The Neutrinos from Stored Muons (nuSTORM) facility will generate neutrino beams from both muon and meson decays in a storage ring, providing a neutrino flux known to the percent le…

Boomerang mechanism explaining the excess radio background

Bhupal Dev, Pasquale Di Bari, Ivan Martinez-Soler +1

We propose a boomerang mechanism for the explanation of the excess radio background detected by ARCADE 2. In an early stage of the Universe, at a temperature $T$ in the range $\sim…

Sensitivity of $W$ -boson measurements to low-mass right-handed neutrinos

Rodrigo Alonso, Sam Bates, Chris Hays +2

A low-mass right-handed neutrino could interact with electroweak bosons via mixing, a mediator particle, or loop corrections. Using an effective field theory, we determine constrai…
