The prospects of measuring the CKM matrix elements |V\_tq| with top quarks
decays at the LHC are discussed here, with the top quarks produced in the
processes pp ttbarX and pp t/tbarX, and the subsequent
decays t Ws and/or tbar Wsbar. As for the direct
measurement of |V\_tb|, there is also a lot of interest in the direct
measurements of |V\_ts| and |V\_td|, as the absolute values of these CKM matrix
elements can be modified by approximately a factor 2 from their SM values.
Direct determination of these matrix elements will require a good tagging of
the t s transition (for |V\_ts|) and t d transition (for
|V\_td|) in the top quark decays, and a very large top quark statistics, which
is available at the LHC. Lacking a good tagging for the t d
transition, and also because of the small size of the CKM-matrix element,
|V\_td| = O(10^-2), direct measurements of |V\_ts| at the LHC with main emphasis
at the centre of mass energy sqrt(s) of 14 TeV/c^2 based on the PLB paper of
Ali et al. 1 are shown. Alternative methods for direct |V\_tq| determination
at the LHC are also reported.
