Abstract

After a brief outline of general aspects of conformal field theories in coordinate space, in a first part we review the solution of the conformal constraints of three- and four-point functions in momentum space in dimensions $d\geq 2$, in the form of conformal Ward identities (CWI's). We center our discussion on the analysis of correlators containing stress-energy tensors $(T)$, conserved currents $(J)$, and scalar operators $(O)$. For scalar four-point functions, we briefly discuss our method for determining the dual conformal solutions of such equations, identified only by the CWI's, and related to the conformal Yangian symmetry, introduced by us in previous work. In correlation functions with $T$ tensors, evaluated around a flat spacetime, the conformal anomaly is characterized by the (non-local) exchange of massless poles in specific form factors, a signature that has been investigated both in free field theory and non-perturbatively, by solving the conformal constraints. We discuss the anomaly effective action, and illustrate the derivation of the CWI's directly from its path integral definition and its Weyl symmetry, which is alternative to the standard operatorial approach used in conformal field theories in flat space. For two- and three-point functions, we elaborate on the matching of these types of correlators to free-field theories. Perturbative realizations of CFTs at one-loop provide the simplest expressions of the general solutions identified by the CWI's, for generic operators $T$, $J$, and scalars of specific scaling dimensions, by an appropriate choice of their field content. In a technical appendix we offer details on the reconstruction of the $TTO$ and $TTT$ correlators in the approach of Bzowski, McFadden and Skenderis, and specifically on the secondary Ward identities of the method, in order to establish a complete match with the perturbative description., 110 pages, 5 Figures.

Abstract

We present a general study of 3-point functions of conformal field theory in momentum space, following a reconstruction method for tensor correlators, based on the solution of the conformal Ward identities (CWI' s), introduced in recent works by Bzowski, McFadden and Skenderis (BMS). We investigate and detail the structure of the CWI's, their non-perturbative solutions and the transition to momentum space, comparing them to perturbation theory by taking QED as an example. We then proceed with an analysis of the $TJJ$ correlator, presenting independent and detailed re-derivations of the conformal equations in the reconstruction method of BMS, originally formulated using a minimal tensor basis in the transverse traceless sector. A careful comparison with a second basis introduced in previous studies shows that this correlator is affected by one anomaly pole in the graviton (T) line, induced by renormalization. The result shows that the origin of the anomaly, in this correlator, should be necessarily attributed to the exchange of a massless effective degree of freedom. Our results are then exemplified in massless QED at one-loop in $d$-dimensions, expressed in terms of perturbative master integrals. An independent analysis of the Fuchsian character of the solutions, which bypasses the 3K integrals, is also presented. We show that the combination of field theories at one-loop - with a specific field content of degenerate massless scalar and fermions - is sufficient to generate the complete non-perturbative solution, in agreement with a previous study in coordinate space. The result shows that free conformal field theories, in specific dimensions, arrested at one-loop, reproduce the general result for the $TJJ$. Analytical checks of this correspondence are presented in $d=3,4$ and $5$ spacetime dimensions[..]., 79 pages, 3 Figures. Final version, with changes in section 8.

Abstract

See editorial on page 284. BACKGROUND & AIMS: The presence of celiac diseaseassociated autoantibodies (antiendomysium and antitissue transglutaminase [anti-TG2]) with normal jejunal mucosa indicate potential celiac disease. We performed a prospective, 3-year cohort study to determine the natural history of potential celiac disease in children. METHODS: The study included 106 children with potential celiac disease, based on serology analysis and normal duodenal architecture. All but 2 carried the HLA-DQ2 and/or DQ8 haplotype. In all children, every 6 months, growth, nutritional parameters, celiac disease serology, and autoimmunity were investigated. In biopsies, intraepithelial-, CD3-, and lamina propria CD25-positive cells were counted; duodenal deposits of anti-TG2 immunoglobulin A were detected. Biopsy analysis was repeated after 2 years on patients with persistent positive serology and/or symptoms. RESULTS: Celiac disease was detected primarily in firstdegree relatives and patients with autoimmune disorders (40.6%). A gluten-free diet was prescribed to 20/106 patients because of symptoms, which were relieved in only 11. Eightynine of the 106 patients entered the follow-up study, with normal daily consumption of gluten. During the follow-up antibodies disappeared in 14.6% and fluctuated in 32.6%. Villous atrophy was observed in 12/39 patients (30.8%) who underwent a repeat biopsy. CONCLUSIONS: Most children with potential celiac disease remain healthy. After 3 years, approximately 33% of patients develop villous atrophy. Intestinal deposits of anti-TG2 IgA identify children at risk for villous atrophy.
