Schwinger-Dyson equations in QED and QCD the calculation of fermion-antifermion condensates [PDF]
, 2007 We present non-perturbative solutions for the fermion and boson propagators of QED in both three- and four-dimensions, and QCD. In doing so, we solve the coupled system of Schwinger-Dyson equations numerically in Euclidean space, investigating ...

Measuring quantum discord at the LHC
Journal of High Energy PhysicsThere has been an increasing interest in exploring quantities associated with quantum information at colliders. We perform a detailed analysis describing how to measure the quantum discord in the top anti-top quantum state at the Large Hadron Collider ...

Scalar mesons and tetraquarks by means of lattice QCD [PDF]
, 2012 We study the light scalar mesons a_0(980) and kappa using N_f = 2+1+1 flavor lattice QCD. In order to probe the internal structure of these scalar mesons, and in particular to identify, whether a sizeable tetraquark component is present, we use a large ...

QCD phenomenology in tachyon condensation theory [PDF]
, 2021 This thesis is intended to contribute to the long standing problems associated with theoretical QCD theory. We aim at touching on all possible QCD features such as; color confinement, asymptotic freedom and chiral symmetry breaking.

Local vs. nonlocal entanglement in top-quark pairs at the LHC
Journal of High Energy PhysicsWe show that the entanglement observed in top-antitop quark spin states at the LHC is local in the energy region close to the production threshold. In contrast, nonlocal entanglement is observed in the central boosted region defined by a top-quark pair ...

Non-perturbative effects in Higgs boson decays to electroweak vector bosons and photons
Journal of High Energy PhysicsWe estimate the magnitude of the leading non-perturbative QCD corrections to the decays of the Higgs boson to the γZ and γγ final states. These corrections originate from the light-quark contributions to such decays.

RS-invariant resummations of QCD perturbation theory [PDF]
, 1997 We propose a renormalon-inspired resummation of QCD perturbation theory based on approximating the renormalization scheme (RS) invariant effective charge (EC) beta- function coefficients by the portion containing the highest power of b = (11N'-2N(_f))/6,

The baryonic phase in holographic descriptions of the QCD phase diagram
, 2012 We study holographic models of the QCD temperature-chemical potential phase diagram based on the D3/D7 system with chiral symmetry breaking. The baryonic phase may be included through linked D5-D7 systems. In a previous analysis of a model with a running

A particle on a ring or: how I learned to stop worrying and love θ-vacua
Journal of High Energy PhysicsRecently, Ai, Cruz, Garbrecht, and Tamarit (ACGT) [1–3] claimed that the strong CP problem can be avoided by adopting a particular order of limits in the Euclidean path integral, in which the spacetime volume is taken to infinity before summing over all ...
