DESCRIPTION:Speakers: Ryan Hill ()\nB mesons are ideally suited to test th
 e Standard Model Flavour Sector through experimental measurements of the C
 KM matrix elements |V_ub| and |V_cb|. Theoretical calculations of these ma
 trix elements are also required\, which is where lattice QCD steps in. How
 ever\, heavy quarks cannot be placed on the lattice in the same manner as 
 light quarks. The lattice introduces discretisation errors that are propor
 tional to ma\, the product of the quark mass and lattice spacing. If this 
 product is of order unity or above\, as is the case for heavy quarks on cu
 rrent lattices\, the discretisation errors become uncontrolled. This talk 
 will primarily discuss how an anisotropic fermion action (the Relativistic
  Heavy Quark action) can be used to circumvent this discretisation problem
 \, and enable simulations of semi-leptonic B meson decays to calculate the
 oretical values for |V_ub| and |V_cb|.\n\nhttps://indico.ific.uv.es/event/
