Typos corrected, reference added, version to appear in Phys. Rev. D. arXiv admin note: text overlap with arXiv:0910.2419 en dc.description.abstract The masses of the low-lying strange and charm baryons are evaluated using two degenerate flavors of twisted mass sea quarks for pion masses in the range of about 260 MeV to 450 MeV. The strange and charm valence quark masses are tuned to reproduce the mass of the kaon and D-meson at the physical point. The tree-level Symanzik improved gauge action is employed. We use three values of the lattice spacing, corresponding to $\beta=3.9$, $\beta=4.05$ and $\beta=4.2$ with $r_0/a=5.22(2)$, $r_0/a=6.61(3)$ and $r_0/a=8.31(5)$ respectively. %spacings $a=0.0855(5)$ and $a=0.0667(3)$ determined from the pion decay constant. We examine the dependence of the strange and charm baryons on the lattice spacing and strange and charm quark masses. The pion mass dependence is studied and physical results are obtained using heavy baryon chiral perturbation theory to extrapolate to the physical point. en dc.language.iso en en dc.subject hep-lat en dc.subject hep-lat en dc.subject hep-ph en dc.subject nucl-th en dc.title Strange and charm baryon masses with two flavors of dynamical twisted mass fermions en dc.type Journal Article plymouth.author-url http://arxiv.org/abs/1205.6856v2 en plymouth.publisher-url http://dx.doi.org/10.1103/PhysRevD.86.114501 en dc.identifier.doi 10.1103/PhysRevD.86.114501 en plymouth.organisational-group /Plymouth plymouth.organisational-group /Plymouth/00 Groups by role plymouth.organisational-group /Plymouth/00 Groups by role/Academics plymouth.organisational-group /Plymouth/Faculty of Science and Engineering plymouth.organisational-group /Plymouth/Faculty of Science and Engineering/School of Computing, Electronics and Mathematics plymouth.organisational-group /Plymouth/REF 2021 Researchers by UoA plymouth.organisational-group /Plymouth/REF 2021 Researchers by UoA/UoA10 Mathematical Sciences dc.rights.embargoperiod No embargo en rioxxterms.versionofrecord 10.1103/PhysRevD.86.114501 en rioxxterms.licenseref.uri http://www.rioxx.net/licenses/all-rights-reserved en rioxxterms.type Journal Article/Review en
