Meson masses and decay constants at large $N$

Understand

Meson masses and decay constants in the large $N$ limit of SU($N$) gauge theory are determined using the twisted Eguchi-Kawai reduced model.

• To this end, we make use of a recently defined smearing method valid on the one-point lattice.
• This procedure, in combination with a variational analysis, allows to obtain reliable values for these quantities.
