Confinement without symmetry breaking in chiral gauge theories
Haolin Li, Álvaro Pastor-Gutiérrez, Shahram Vatani
The infrared structure of gauge theories with chiral fermions remains largely unexplored. In this work we investigate the Bars-Yankielowicz class using the functional renormalisati…
Probing Large Through Schemes
Alan Pinoy, Shahram Vatani
We investigate the reliability of the large expansion of four-dimensional gauge-fermion quantum field theories, focusing on the structure and scheme dependence of the beta fu…
Dynamical symmetry breaking in Georgi-Glashow chiral-gauge theories
Hao-Lin Li, Álvaro Pastor-Gutiérrez, Shahram Vatani +1
We investigate dynamical symmetry breaking in a class of chiral gauge theories containing the Georgi-Glashow model. These theories feature a gauge sector and two fermion species th…
Consistency Relation for Fixed Point Dynamics
Oleg Antipin, Alan Pinoy, Francesco Sannino +1
We gain insight on the fixed point dynamics of dimensional quantum field theories by exploiting the critical behavior of the sister theories. To this end we first derive…
Is the muon a third family lepton?
Giacomo Cacciapaglia, Aldo Deandrea, Shahram Vatani
We propose a new family structure for the Standard Model fermions, where the muon is assigned to the third family, taking the placeholder from the tau lepton. This reassignment, wh…
Variant-driven multi-wave pattern of COVID-19 via a Machine Learning analysis of spike protein mutations
Adele de Hoffer, Shahram Vatani, Corentin Cot +7
Applying a ML approach to the temporal variability of the Spike protein sequence enables us to identify, classify and track emerging virus variants. Our analysis is unbiased, in th…
Epidemiological theory of virus variants
Giacomo Cacciapaglia, Corentin Cot, Adele de Hoffer +3
We propose a physical theory underlying the temporal evolution of competing virus variants that relies on the existence of (quasi) fixed points capturing the large time scale invar…
The field theoretical ABC of epidemic dynamics
Giacomo Cacciapaglia, Corentin Cot, Michele Della Morte +3
Infectious diseases are a threat for human health with tremendous impact on our society at large. The recent COVID-19 pandemic, caused by the SARS-CoV-2, is the latest example of a…
The Techni-Pati-Salam Composite Higgs
Giacomo Cacciapaglia, Shahram Vatani, Chen Zhang
Composite Higgs models can be extended to the Planck scale by means of the partially unified partial compositeness (PUPC) framework. We present in detail the Techni-Pati-Salam mode…
Large for multiple representations
Giacomo Cacciapaglia, Shahram Vatani
We present an extension of the large formalism that allows to study cases with multiple fermion representations. The pole structure in the beta function is traced back to the…
Composite Higgs Meets Planck Scale: Partial Compositeness from Partial Unification
Giacomo Cacciapaglia, Shahram Vatani, Chen Zhang
Providing an Ultra-Violet completion valid up to the Planck scale is of paramount importance to validate the composite Higgs paradigm, at par with supersymmetry. We propose the fir…
Tumbling to the Top
Giacomo Cacciapaglia, Shahram Vatani, Zhi-Wei Wang
We propose a new mechanism to generate the couplings of the top quark to a composite Goldstone Higgs, which we dub {\it Global Extended Technicolor} (GETC). Top, techni-fermions an…
Towards a fundamental safe theory of composite Higgs and Dark Matter
Giacomo Cacciapaglia, Teng Ma, Shahram Vatani +1
We present a novel paradigm that allows to define a composite theory at the electroweak scale that is well defined all the way up to any energy by means of safety in the UV. The th…
