タイトル: New results on strongly-coupled theories near the conformal window
概要:
Lattice gauge theory is a robust framework to study non-perturbative physics
and it is amenable to numerical simulations. It has been successfully used to
study the low-energy regime of QCD. Modern-day lattice simulation codes are
actually flexible enough that users can change the theory being simulated: we
can study different number of colors $N_c$, number of quarks $N_f$ and quarks
in different representations $N_r$, in addition to the usual parameters, gauge
coupling $\beta$ and quark masses $m_f$.These new theories, although
interesting in their own rights as well-defined gauge theories, can be used as
templates to study physics beyond the Standard Model (BSM). In particular, as
tentative candidates for a dynamical mechanism to break the electroweak
symmetry and replace the Higgs sector, they need to be close to the conformal
window in order to satisfy stringent experimental constraints. I will report on
a particular SU(3) gauge theory with 8 fermions in the fundamental
representation. In particular I will highlight how lattice simulations of
the flavor-singlet scalar and pseudoscalar spectrum compare to QCD and how the
observed features in the spectrum indicate the possibility that the theory is
very close to the conformal window.
