Review of lattice results concerning low energy particle physics
Sinya Aoki, Yasumichi Aoki, Claude Bernard +25
We review lattice results related to pion, kaon, D- and B-meson physics with the aim of making them easily accessible to the particle physics community. More specifically, we repor…
Corrections to the Banks-Casher relation with Wilson quarks
S. Necco, A. Shindler
The Banks-Casher relation links the spectral density of the Dirac operator with the existence of a chiral condensate and spontaneous breaking of chiral symmetry. This relation rece…

We study the finite-size scaling of heavy-light mesons in the static limit. The most relevant effects are due to the pseudo-Goldstone boson cloud. In the HMChPT framework we comput…
