Renormalization Group Invariants in Supersymmetric Theories

Published:Dec 29, 2025 17:43
1 min read
ArXiv

Analysis

This paper summarizes and reviews recent advancements in understanding the renormalization of supersymmetric theories. The key contribution is the identification and construction of renormalization group invariants, quantities that remain unchanged under quantum corrections. This is significant because it provides exact results and simplifies calculations in these complex theories. The paper explores these invariants in various supersymmetric models, including SQED+SQCD, the Minimal Supersymmetric Standard Model (MSSM), and a 6D higher derivative gauge theory. The verification through explicit three-loop calculations and the discussion of scheme-dependence further strengthen the paper's impact.
Reference

The paper discusses how to construct expressions that do not receive quantum corrections in all orders for certain ${\cal N}=1$ supersymmetric theories, such as the renormalization group invariant combination of two gauge couplings in ${\cal N}=1$ SQED+SQCD.

Analysis

This paper proposes a factorized approach to calculate nuclear currents, simplifying calculations for electron, neutrino, and beyond Standard Model (BSM) processes. The factorization separates nucleon dynamics from nuclear wave function overlaps, enabling efficient computation and flexible modification of nucleon couplings. This is particularly relevant for event generators used in neutrino physics and other areas where accurate modeling of nuclear effects is crucial.
Reference

The factorized form is attractive for (neutrino) event generators: it abstracts away the nuclear model and allows to easily modify couplings to the nucleon.

Mixed Noise Protects Entanglement

1 min read
ArXiv

Analysis

This paper challenges the common understanding that noise is always detrimental in quantum systems. It demonstrates that specific types of mixed noise, particularly those with high-frequency components, can actually protect and enhance entanglement in a two-atom-cavity system. This finding is significant because it suggests a new approach to controlling and manipulating quantum systems by strategically engineering noise, rather than solely focusing on minimizing it. The research provides insights into noise engineering for practical open quantum systems.
Reference

The high-frequency (HF) noise in the atom-cavity couplings could suppress the decoherence caused by the cavity leakage, thus protect the entanglement.

Analysis

This paper explores the unification of gauge couplings within the framework of Gauge-Higgs Grand Unified Theories (GUTs) in a 5D Anti-de Sitter space. It addresses the potential to solve Standard Model puzzles like the Higgs mass and fermion hierarchies, while also predicting observable signatures at the LHC. The use of Planck-brane correlators for consistent coupling evolution is a key methodological aspect, allowing for a more accurate analysis than previous approaches. The paper revisits and supplements existing results, including brane masses and the Higgs vacuum expectation value, and applies the findings to a specific SU(6) model, assessing the quality of unification.

The paper finds that grand unification is possible in such models in the presence of moderately large brane kinetic terms.

Analysis

This paper investigates the impact of non-local interactions on the emergence of quantum chaos in Ising spin chains.

ArXiv

Analysis

This paper investigates a mechanism for reheating the universe after inflation, focusing on a Higgs inflationary scenario. It explores how gravitational effects alone can create particles and initiate the standard thermal history, particularly in models without direct inflaton couplings. The study's significance lies in providing a potential solution to the reheating problem in minimal inflationary models, demonstrating that gravity can play a crucial role in the early universe's evolution.
Reference

The rapid, oscillatory evolution of the curvature scalar after inflaton acts as a time dependent gravitational pump, creating scalar spectator particles even in the absence of explicit interactions.
