SUMMARY:b-&gt\;c semileptonic decays and phenomenology - Andrew Lytle (INF

DESCRIPTION:There are several long-standing discrepancies between observab
 les in b->c semileptonic decays and their Standard Model predictions. Ther
 e is also a long-standing tension between inclusive and exclusive determin
 ations of Vcb\, the latter being obtained from these same decays. At the s
 ame time a wealth of new experimental information in these decays is becom
 ing available\, and thus it is a challenge to the theory community to keep
  pace with these developments. Here I will review the state-of-the-art in 
 lattice QCD simulations addressing these issues. After reviewing the statu
 s of B->D(*) form factors and measurements I will discuss in more detail n
 ew results from HPQCD that treat the 'b' quark fully relativistically.
