Composite Higgs Dynamics on the Lattice
Claudio Pica, Vincent Drach, Martin Hansen +1
We investigate the spectrum of the SU(2) gauge theory with = 2 flavors of fermions in the fundamental representation, in the continuum, using lattice simulations. This model…
Viscous Conformal Gauge Theories
Arianna Toniato, Francesco Sannino, Dirk H. Rischke
We present the conformal behavior of the shear viscosity-to-entropy density ratio and the fermion-number diffusion coefficient within the perturbative regime of the conformal windo…
Adjoint SU(2) with Four Fermion Interactions
Jarno Rantaharju, Vincent Drach, Claudio Pica +1
Four fermion interactions appear in many models of Beyond Standard Model physics. In Technicolour and composite Higgs models Standard Model fermion masses can be generated by four…
Inflation and pseudo-Goldstone Higgs boson
Tommi Alanne, Francesco Sannino, Tommi Tenkanen +1
We consider inflation within a model framework where the Higgs boson arises as a pseudo-Goldstone boson associated with the breaking of a global symmetry at a scale significantly l…
Asymptotically Safe Grand Unification
Borut Bajc, Francesco Sannino
Phenomenologically appealing supersymmetric grand unified theories have large gauge representations and thus are not asymptotically free. Their ultraviolet validity is limited by t…
Asymptotically safe and free chiral theories with and without scalars
Esben Molgaard, Francesco Sannino
We unveil the dynamics of four dimensional chiral gauge-Yukawa theories featuring several scalar degrees of freedom transforming according to distinct representations of the underl…
Extending Chiral Perturbation Theory with an Isosinglet Scalar
Martin Hansen, Kasper Langaeble, Francesco Sannino
We augment the chiral Lagrangian by an isosinglet scalar and compute the one-loop radiative corrections to the pion mass and decay constant, as well as the scalar mass. The calcula…
Nambu-Jona-Lasinio model with Wilson fermions
Jarno Rantaharju, Vincent Drach, Claudio Pica +1
We present a lattice study of a Nambu Jona-Lasinio (NJL) model using Wilson fermions. Four fermion interactions are a natural part of several extensions of the Standard Model, appe…
Vacuum alignment with(out) elementary scalars
Tommi Alanne, Helene Gertov, Aurora Meroni +1
We systematically elucidate differences and similarities of the vacuum alignment issue in composite and renormalizable elementary extensions of the Standard Model featuring a pseud…
Gauge Theory with Two Fundamental Flavours: Scalar and Pseudoscalar Spectrum
Rudy Arthur, Vincent Drach, Ari Hietanen +2
We investigate the scalar and pseudoscalar spectrum of the gauge theory with flavours of fermions in the fundamental representation using non perturbative lattice s…
Fundamental partial compositeness
Francesco Sannino, Alessandro Strumia, Andrea Tesi +1
We construct renormalizable Standard Model extensions, valid up to the Planck scale, that give a composite Higgs from a new fundamental strong force acting on fermions and scalars.…
Raising the SUSY-breaking scale in a Goldstone-Higgs model
Tommi Alanne, Heidi Rzehak, Francesco Sannino +1
We show that by combining the elementary-Goldstone-Higgs scenario and supersymmetry it is possible to raise the scale of supersymmetry breaking to several TeVs by relating it to th…
Conformal Phase Diagram of Complete Asymptotically Free Theories
Claudio Pica, Thomas A. Ryttov, Francesco Sannino
We investigate the ultraviolet and infrared fixed point structure of gauge-Yukawa theories featuring a single gauge coupling, Yukawa coupling and scalar self coupling. Our investig…
Anomalous Dimensions of Conformal Baryons
Claudio Pica, Francesco Sannino
We determine the anomalous dimensions of baryon operators for the three color theory as function of the number of massless flavours within the conformal window to the maximum known…
Collider Tests of (Composite) Diphoton Resonances
Emiliano Molinaro, Francesco Sannino, Natascia Vignaroli
We analyze the Large Hadron Collider sensitivity to new pseudoscalar resonances decaying into diphoton with masses up to scales of few TeVs. We focus on minimal scenarios where the…
Minimal Composite Dynamics versus Axion Origin of the Diphoton excess
Emiliano Molinaro, Francesco Sannino, Natascia Vignaroli
ATLAS and CMS observe deviations from the expected background in the diphoton invariant mass searches of new resonances around 750 GeV. We show that a simple realization in terms o…
