The conservation of the vector current and the axial anomaly responsible for the $\pi_0 \to \gamma \gamma$ decay amplitude are obtained in leading order within the Taylor-Lagrange formulation of fields considered as operator-valued distributions. As

Light-front and conformal field theories in two dimensions

Light-front (LF) quantization of massless fields in two spacetime dimensions is a long-standing and much debated problem. Even though the classical wave-equation is well-documented for almost two centuries, either as problems with initial values in s

Two-dimensional models with massless fermions (Thirring model, Thirring–Wess and Schwinger model, among others) have been solved exactly a long time ago in the conventional (space-like) form of field theory and in some cases also in the conformal f

Quantum field theory formulated in terms of light front (LF) variables has a few attractive as well as some puzzling features. The latter hindered a wider acceptance of LF methods. In two space–time dimensions, it has been a long-standing puzzle ho

Differentiable simulation of a liquid argon time projection chamber

Autor: Sean Gasiorowski, Yifan Chen, Youssef Nashed, Pierre Granger, Camelia Mironov, Ka Vang Tsang, Daniel Ratner, Kazuhiro Terao

Publikováno v: Machine Learning: Science and Technology, Vol 5, Iss 2, p 025012 (2024)

Liquid argon time projection chambers (LArTPCs) are widely used in particle detection for their tracking and calorimetric capabilities. The particle physics community actively builds and improves high-quality simulators for such detectors in order to

HIGGS MECHANISM IN A LIGHT FRONT FORMULATION

Autor: Pierre Grangé, Lubomir Martinovic

Publikováno v: Modern Physics Letters A. 23:417-425

We give a simple derivation of the Higgs mechanism in an abelian light front field theory. It is based on a finite volume quantization with antiperiodic scalar fields and a periodic gauge field. An infinite set of degenerate vacua in the form of cohe

Dynamical zero modes and criticality in continuous light-cone quantization of Φ1+14

Autor: Pierre Grangé, S. Salmons, E. Werner

Publikováno v: Nuclear Physics B - Proceedings Supplements. 108:208-213

Critical behaviour of the 2D scalar field theory in the LC framework is reviewed. The notion of dynamical zero modes is introduced and shown to lead to a non trivial covariant dispersion relation only for Continuous LC Quantization (CLCQ). The critic

EXACT DUALITY BETWEEN INTEGRABLE DEFORMATIONS OF BCn AND $C_n^{(1)}$ AFFINE TODA THEORIES

Autor: Pascal Baseilhac, Vladimir Fateev, Pierre Grangé

Publikováno v: Modern Physics Letters A. 13:937-951

Integrable deformations of two affine Toda field theories based on BCn and [Formula: see text] non-simply laced algebras are studied. The proof of quantum integrability of the two theories is given and it is shown that the two theories are dual, corr

Continuum version ofφ1+14theory in light-front quantization

Autor: Pierre Grangé, Peter Ullrich, E. Werner

Publikováno v: Physical Review D. 57:4981-4989

A genuine continuum treatment of the massive \phi^4_{1+1}-theory in light-cone quantization is proposed. Fields are treated as operator valued distributions thereby leading to a mathematically well defined handling of ultraviolet and light cone induc

Aspects of fine-tuning of the Higgs mass within finite field theories

Physical Review D, American Physical Society, 2013, 88 (12), pp.125015. ⟨10.1103/PhysRevD.88.125015⟩

We reanalyze the perturbative radiative corrections to the Higgs mass within the Standard Model in the light of the Taylor-Lagrange renormalization scheme. This scheme naturally leads to completely finite corrections, depending on an arbitrary scale.
