Conformal window of SU(N) gauge theories with fermions in higher dimensional representations
- D. Dietrich, Francesco Sannino
- Physics
- 15 April 2007
We study the phase diagram as a function of the number of colors and flavors of asymptotically free nonsupersymmetric theories with matter in higher-dimensional representations of arbitrary SU(N)…
The Physical spectrum of conformal SU(N) gauge theories
- T. Appelquist, Francesco Sannino
- Physics
- 18 June 1998
We investigate the physical spectrum of vector-like SU(N) gauge theories with infrared coupling close to but above the critical value for a conformal phase transition. We use dispersion relations,…
Technicolor walks at the LHC
- A. Belyaev, R. Foadi, M. Frandsen, M. Jarvinen, A. Pukhov, Francesco Sannino
- Physics
- 4 September 2008
We analyze the potential of the Large Hadron Collider (LHC) to observe signatures of phenomenologically viable walking technicolor models. We study and compare the Drell-Yan and vector boson fusion…
Orientifold theory dynamics and symmetry breaking
- Francesco Sannino, K. Tuominen
- Physics
- 21 May 2004
We show that it is possible to construct explicit models of electroweak symmetry breaking in which the number of techniflavors needed to enter the conformal phase of the theory is small and weakly…

Enhanced Global Symmetries and The Chiral Phase Transition
- T. Appelquist, P. D. Silva, Francesco Sannino
- Physics
- 30 June 1999
We examine the possibility that the physical spectrum of a vectorlike gauge field theory exhibits an enhanced global symmetry near a chiral phase transition. A transition from the Goldstone phase to…
Fundamental partial compositeness
- Francesco Sannino, A. Strumia, A. Tesi, Elena Vigiani
- Physics
- 6 July 2016
A bstractWe 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. Yukawa…
Conformal Dynamics for TeV Physics and Cosmology
- Francesco Sannino
- Physics
- 5 November 2009
We introduce the topic of dynamical breaking of the electroweak symmetry and its link to unparticle physics and cosmology. The knowledge of the phase diagram of strongly coupled theories plays a…
Supersymmetry inspired QCD beta function
- T. Ryttov, Francesco Sannino
- Physics
- 23 November 2007
We propose an all orders beta function for ordinary Yang-Mills theories with or without fermions inspired by the Novikov-Shifman-Vainshtein-Zakharov beta function of N=1 supersymmetric gauge…
