A series of key experiments performed about 50 years ago revealed the eminent role of gauge theories. Two theories were formulated: the electroweak theory and the strong interaction theory QCD. An extensive worldwide research programme has since been set up and has step by step corroborated their predictions, while alternative theoretical attempts have been ruled out. Today these theories are well established and represent the cornerstones of the Standard Model.
The main authors, Franz Groß and Eberhard Klempt, succeeded in gathering experts to write articles covering all aspects of the vast field of strong interaction processes, described by Quantum Chromodynamics QCD, the theory of strong interactions. The fruit of their labours is a comprehensive review, ca. 650 pages long, published in the European Physical Journal C (EPJ C). The major aspects are outlined in 14 chapters, each of which is devoted to a specific topic. The authors’ goal was to provide general and detailed insights into both experiment and theory, for the benefit of research students and other interested readers alike.

This EPJ C Topical Collection presents a series of reviews showcasing the latest developments and applications of gauge/gravity duality, and aims at dissemination to a wider physics community in a way that enables building upon these concepts.
The gauge/gravity duality states that gravity and quantum spacetime emerges, i.e. can be reconstructed from a quantum gauge theory living at the boundary. Over the past 25 years, this duality, with concrete instances uncovered by string theory, has revolutionised our understanding of systems ranging from black holes, to matter made up of strongly interacting quantum particles featuring intricate webs of entanglement. In this Topical Collection, the journal EPJ C presents a collection of articles reviewing the latest advances in the fundamental understanding of this duality and its groundbreaking applications.
EPJ C Topical Issue on New frontiers in holographic duality: From quantum complexity and black holes to hydrodynamics and neutron stars
- Published on 20 October 2022
Guest Editor: Ayan Mukhopadhyay
Over the last 25 years, holographic duality has revolutionised our understanding of gauge theories, quantum many-body systems and also quantum black holes. This topical issue is a collection of review articles on recent advances in fundamentals of holographic duality and its applications with special focus on a few areas where it is inter-disciplinary to a large measure. The aim is to provide a sufficient background on relevant phenomenology and other theoretical areas such as quantum information theory to researchers whose primary expertise is in quantum fields, strings and gravity, and also the necessary concepts and methods of holography to researchers in other fields, so that these recent developments could be grasped and hopefully further developed by a wider community.

By decorrelating the performance of machine learning algorithms with imperfections in the simulations used to train them, researchers could be estimating uncertainties that are lower than their true values.
The Standard Model of particle physics offers a robust theoretical picture of the fundamental particles, and most fundamental forces which compose the universe. All the same, there are several aspects of the universe: from the existence of dark matter, to the oscillating nature of neutrinos, which the model can’t explain – suggesting that the mathematical descriptions it provides are incomplete. While experiments so far have been unable to identify significant deviations from the Standard Model, physicists hope that these gaps could start to appear as experimental techniques become increasingly sensitive.
A key element of these improvements is the use of machine learning algorithms, which can automatically improve upon classical techniques by using higher-dimensional inputs, and extracting patterns from many training examples. Yet in new analysis published in EPJ C, Aishik Ghosh at the University of California, Irvine, and Benjamin Nachman at the Lawrence Berkeley National Laboratory, USA, show that researchers using machine learning methods could risk underestimating uncertainties in their final results.

The publishers of The European Physical Journal C - Particles and Fields (EPJ C) are pleased to announce a new structure for the theory sections of the journal. As of January 2022 the current section ‘Theoretical Physics II: Gravitation, Astroparticle Physics, Cosmology, Quantum Field Theories’ (Editor-in-Chief: Prof. Kostas Skenderis, Deputy Editor-in-Chief Prof. Dominik Schwarz) will be split – into ‘Theoretical Physics II: Astroparticle Physics and Cosmology - Models and Phenomenology’, to be headed by Dominik Schwarz; and ‘Theoretical Physics III: Quantum Field Theory and Gravity - Fundamental and Formal Aspects’, to be headed by Kostas Skenderis. This change reflects the rapid development of the current Theoretical Physics II section under Kostas Skenderis over the past few years. We would like to thank Professor Skenderis for his excellent management of the section and to welcome Professor Schwarz as a new Editor-in-Chief of EPJ C. As head of the Astroparticle Physics and Cosmology Working Group at Bielefeld University, Schwarz is an expert on the interfaces between particle physics and cosmology and between modelling and observational cosmology. His research interests include cosmological inflation and the thermal history of the Universe, the cosmic microwave background and large-scale structures, dark matter and dark energy.

Today, Gaussian Processes data reconstruction is viewed as a vital tool in cosmology. Yet through new analysis of tensions in the value of Hubble’s constant, two researchers suggest that the approach may not be as valid as currently thought.
The technique of Gaussian Processes (GP) is widely used to reconstruct cosmological parameters, most notably the expansion rate of the universe, using observational data. For many cosmologists, the crowning achievement of this approach is its ‘model independence’ – meaning it can be applied universally across all models. Through new analysis published in EPJ C, Eoin Ó Colgáin at Sogang University, Seoul, and Mohammad Mehdi Sheikh-Jabbari at IPM, Tehran, use the Hubble constant (H0) to show that this may not be the case – and that it may be time to question the validity of model independence itself.
