Mass estimates of the SU(2) glueball from spectral methods
David Dudal, Orlando Oliveira, Martin Roelfs
The estimation of the Källén-Lehmann spectral density from gauge invariant lattice QCD two point correlation functions is proposed, and explored via an inversion strategy based on…
Gauge Invariant Description of the Higgs model: Ward identities and Renormalization
David Dudal, Duifje Maria van Egmond, Igor Figueiredo Justo +2
The renormalization properties of two local gauge invariant composite operators corresponding, respectively, to the gauge invariant description of the Higgs particle an…
Landau-Khalatnikov-Fradkin transformations for the two loop massless quark propagator
Pietro Dall'Olio, Tim De Meerleer, David Dudal +2
Landau-Khalatnikov-Fradkin transformations (LKFTs) yield the gauge dependence of correlation functions within the class of linear covariant gauges. We derive the LKFT for the quark…
The Abelian Higgs model under a gauge invariant looking glass: exploiting new Ward identities for gauge invariant operators and the Equivalence Theorem
D. Dudal, G. Peruzzo, S. P. Sorella
The content of two additional Ward identities exhibited by the Higgs model is exploited. These novel Ward identities can be derived only when a pair of local composite opera…
Källén-Lehmann Spectral Representation of the Scalar SU(2) Glueball
David Dudal, Orlando Oliveira, Martin Roelfs
The estimation of the Källén-Lehmann spectral density from gauge invariant lattice QCD two point correlation functions is proposed, and explored via an appropriate inversion method…
Half-integer anomalous currents in 2D materials from a QFT viewpoint
D. Dudal, F. Matusalem, A. J. Mizher +2
Charge carriers in Dirac/Weyl semi-metals exhibit a relativistic-like behavior. In this work we propose a novel type of intrinsic half-integer Quantum Hall effect in 2D materials,…
