Abstract

We study the behaviour of spin 1/2 charmed baryons as the temperature increases. We make use of anisotropic lattice QCD simulations with N f = 2+1 dynam- ical flavours. After determining the positive and negative par- ity ground state masses at the lowest temperature, we inves- tigate the effect of...
