We present results on the light, strange and charm nucleon scalar and tensor charges from lattice QCD, using simulations with Nf=2 flavors of twisted mass clover-improved fermions with a physical… Expand

Low-lying baryon masses using $N_f=2$ twisted mass clover-improved fermions directly at the physical pion mass

- C. Alexandrou, C. Kallidonis
- Physics
- 9 April 2017

The masses of the low-lying baryons are evaluated using an ensemble with two degenerate light twisted mass clover-improved quarks with mass tuned to reproduce the physical pion mass. The Iwasaki… Expand

Baryon spectrum with $N_f=2+1+1$ twisted mass fermions
