Can we make sense out of negative kinetic energy?
Alessio Maiezza, Fabrizio Nesti
Many Quantum Field Theory models, either designed to improve the ultraviolet behavior via higher derivative terms or aimed at providing unified descriptions of Gravity, inevitably…
Universal Emergence of Bosonic and Fermionic Algebras in a Deterministic Proper-Time Framework
Alessio Maiezza
This work develops the deterministic, discrete proper-time framework introduced in our previous work, Eur.\ Phys.\ J.\ C \textbf{86} (2026) 829, in which quantum field theory emerg…
Minimal Proper Time and Deterministic Microstates: Emergent Quantum Fields and Relativistic Spacetime
Alessio Maiezza
We develop a top-down counterpart of the minimal proper-time formulation of quantum field theory previously introduced as an effective bottom-up framework. Starting from a determin…
Minimal Proper-time in Quantum Field Theory
Alessio Maiezza, Juan Carlos Vasquez
We propose a generalization of quantum field theory within Schrodinger's functional representation, inspired by Nambu's proper-time formulation of quantum mechanics. The key motiva…
Quantum Field Theory on Multifractal Spacetime: Varying Dimension and Ultraviolet Completeness
Alessio Maiezza, Juan Carlos Vasquez
Inspired by various quantum gravity approaches, we explore quantum field theory where spacetime exhibits scaling properties and dimensional reduction with changing energy scales, e…
Uncovering Hidden Patterns: Approximate Resurgent Resummation from Truncated Series
Alessio Maiezza, Juan Carlos Vasquez
We analyze truncated series generated as divergent formal solutions of non-linear ordinary differential equations. Motivating the study is a specific non-linear, first-order differ…
Renormalization group flows and emergent symmetries
Zurab Berezhiani, Maicol Di Giambattista, Alessio Maiezza +1
We discuss the following proposition: Renormalization Group flow of quantum theory with a biased symmetry exhibits a fixed hypersurface at which the symmetry is exact. Such emergen…
Gluon Mass Generation from Renormalons and Resurgence
Alessio Maiezza, Juan Carlos Vasquez
We establish a link between the concepts of infrared renormalons, infrared fixed point, and dynamical nonperturbative mass generation of gluons in pure Yang-Mills theories. By util…
Resurgence and self-completion in renormalized gauge theories
Alessio Maiezza, Juan Carlos Vasquez
Under certain assumptions and independent of the instantons, we show that the logarithm expansion of dimensional regularization in quantum field theory needs a nonperturbative comp…
Neutrinoless double beta decay: neutrino mass versus new physics
Gia Dvali, Alessio Maiezza, Goran Senjanovic +1
Neutrinoless double beta decay is the textbook example of lepton number violation, often claimed to be a probe of neutrino Majorana mass. However, it could be triggered by new phys…
A consistent quantum field theory from dimensional reduction
Alessio Maiezza, Juan Carlos Vasquez
We incorporate the concept of dimensional reduction at high energies within the perturbative formulation of quantum field theory. In this new framework, space and momentum integrat…
Parity from gauge symmetry
Alessio Maiezza, Fabrizio Nesti
We argue that Left-Right parity symmetry can arise as a discrete remnant of a unified gauge symmetry. The high-energy unification necessarily includes the gauging of…
The QCD Adler function and the muon anomaly from renormalons
Alessio Maiezza, Juan Carlos Vasquez
We describe the Adler function in Quantum Chromodynamics using a transseries representation within a resurgent framework. The approach is based on a Borel-Ecalle resummation of the…
Resurgence of the QCD Adler function
Alessio Maiezza, Juan Carlos Vasquez
We study the QCD Adler function in the energy region GeV, in which the non-perturbative effects become dominant. Our analysis is a renormalon-based evaluation usi…
Quark mixing with soft breaking of the parity in the minimal Left-Right model
Alessio Maiezza
We study the possibility of soft breaking effects of the generalized parity within the minimal Left-Right model. One aim of the paper is to elaborate on the potentiality, the limit…
On Haag's theorem and renormalization ambiguities
Alessio Maiezza, Juan Carlos Vasquez
We revisit the implications of Haag's theorem in the light of the renormalization group. There is still some lack of discussion in the literature about the possible impact of the t…
Non-Wilsonian ultraviolet completion via transseries
Alessio Maiezza, Juan Carlos Vasquez
We study some of the implications for the perturbative renormalization program when augmented with the Borel-Ecalle resummation. We show the emergence of a new kind of non-perturba…
Kaon CP violation and neutron EDM in the minimal left-right symmetric model
Stefano Bertolini, Alessio Maiezza, Fabrizio Nesti
Within the minimal Left-Right (LR) symmetric model we revisit the predictions for the kaon CP violating observables and in correlation with the neutron…
Resurgence of the Renormalization Group Equation
Jahmall Bersini, Alessio Maiezza, Juan Carlos Vasquez
We show how the renormalons emerge from the renormalization group equation with a priori no reference to any Feynman diagrams. The proof is rather given by recasting the renormaliz…
Non-local Lagrangians from Renormalons and Analyzable Functions
Alessio Maiezza, Juan Carlos Vasquez
We embed in a generalized Borel procedure the notion of renormalization and renormalons. While there are several efforts in literature to have a semi-classical understanding of the…
Resummation in QFT with Meijer G-functions
Oleg Antipin, Alessio Maiezza, Juan Carlos Vasquez
We employ a recent resummation method to deal with divergent series, based on the Meijer G-function, which gives access to the non-perturbative regime of any QFT from the first few…
Multifield Polygonal Bounces
Victor Guada, Alessio Maiezza, Miha Nemevšek
We propose a new approach for computing tunneling rates in quantum or thermal field theory with multiple scalar fields. It is based on exact analytical solutions of piecewise linea…
Resummation and renormalons in a general Quantum Field Theory
Alessio Maiezza, Juan Carlos Vasquez
We generalize the concept of Borel resummability and renormalons to a quantum field theory with an arbitrary number of fields and couplings, starting from the known notion based on…
Higgs Sector of the Left-Right Symmetric Theory
Alessio Maiezza, Goran Senjanović, Juan Carlos Vasquez
We perform an in-depth analysis of the Higgs sector in the Minimal Left-Right Symmetric Model and compute the scalar mass spectrum and associated mixings, offering simple physical…
