Inflation, Leptogenesis, and Yukawa Quasi-Unification within a Supersymmetric Left-Right Model
R. Armillis, G. Lazarides, C. Pallis
A simple extension of the minimal left-right symmetric supersymmetric grand unified theory model is constructed by adding two pairs of superfields. This naturally violates the part…
Spontaneously Broken Conformal Symmetry: Dealing with the Trace Anomaly
Roberta Armillis, Alexander Monin, Mikhail Shaposhnikov
The majority of renormalizable field theories possessing the scale invariance at the classical level exhibits the trace anomaly once quantum corrections are taken into account. Thi…
Implementing Hilltop F-term Hybrid Inflation in Supergravity
R. Armillis, C. Pallis
F-term hybrid inflation (FHI) of the hilltop type can generate a scalar spectral index, ns, in agreement with the fitting of the seven-year Wilkinson microwave anisotropy probe dat…
Comments on Anomaly Cancellations by Pole Subtractions and Ghost Instabilities with Gravity
Roberta Armillis, Claudio Coriano, Luigi Delle Rose +1
We investigate some aspects of anomaly cancellation realized by the subtraction of an anomaly pole, stressing on some of its properties in superspace. In a local formulation these…
The Trace Anomaly and the Couplings of QED and QCD to Gravity
Roberta Armillis, Claudio Coriano, Luigi Delle Rose
We report on the computation of the effective actions describing the interaction of gravity both for an abelian and a non-abelian gauge theory, mediated by the trace anomaly.
Trace Anomaly, Massless Scalars and the Gravitational Coupling of QCD
Roberta Armillis, Claudio Coriano, Luigi Delle Rose
The anomalous effective action describing the coupling of gravity to a non-abelian gauge theory can be determined by a variational solution of the anomaly equation, as shown by Rie…
The Trace Anomaly and the Gravitational Coupling of an Anomalous U(1)
Roberta Armillis, Claudio Coriano, Luigi Delle Rose +1
We extend a previous computation of the TJJ correlator, involving the energy-momentum tensor of an abelian gauge theory and two vector currents, to the case of mixed axial-vector/v…
The Effective Actions of Pseudoscalar and Scalar Particles in Theories with Gauge and Conformal Anomalies
Roberta Armillis, Claudio Coriano, Luigi Delle Rose +2
We review recent work on the effective field theory description and the phenomenology of axion-like and scalar particles in models characterized by gauge and/or conformal anomalies…
Anomaly Poles as Common Signatures of Chiral and Conformal Anomalies
Roberta Armillis, Claudio Coriano, Luigi Delle Rose
One feature of the chiral anomaly, analyzed in a perturbative framework, is the appearance of massless poles which account for it. They are identified by a spectral analysis of the…
Trilinear Gauge Interactions in Extensions of the Standard Model and Unitarity
Roberta Armillis, Claudio Coriano, Luigi Delle Rose
We summarize recent work on the characterization of anomaly poles in connection with the field-theory interpretation of the Green-Schwarz mechanism of anomaly cancellation and on t…
Anomalous U(1) Models in Four and Five Dimensions and their Anomaly Poles
Roberta Armillis, Claudio Coriano, Luigi Delle Rose +1
We analyze the role played by anomaly poles in an anomalous gauge theory by discussing their signature in the corresponding off-shell effective action. The origin of these contribu…

Roberta Armillis, Claudio Coriano', Marco Guzzi +1
We quantify the impact of gauge anomalies at the Large Hadron Collider by studying the invariant mass distributions in Drell-Yan and in double prompt photon, using an extension of…
