"It was a journey of faith, and God taught me resilience." And Graham's journey of faith continues, as she serves as the FCNC at Texas Health Plano.
The effective Hamiltonian of several FCNC processes [23, 24], semileptonic and radiative decays of B mesons [25-33], and FCNC baryonic decays [34-36] have been investigated in the ACD model.
Further evidence for this discreteness might be the appearance of a b' quark at about 80-100 GeV decaying via FCNC to a b quark plus a photon at the Large Hadron Collider.
This comparison not only helps to place bounds (listed in Tables 2, 4, and 5) on [[??].sub.p] Yukawa couplings [[lambda]'.sub.[alpha]k[beta]][[lambda]'.sup.*.sub.[alpha]k[gamma]] but also enables to predict (listed in Tables 3, 6-9) the enhancement of similar processes (having identical FCNC).
This mixing leads to the FCNC appearing at the tree level.
At quark level, the decay [B.sup.+.sub.c] [right arrow][D.sup.+][nu][bar.[nu]] proceeds via b [right arrow] d FCNC transition with the intermediate u, c, and t quarks and most of the contribution comes from the intermediate t quark.
The CDF experiment set upper bound on branching ratio for top quark FCNC decay as BR(t [right arrow] q[gamma]) < 3.2 x [10.sup.-2] [5].
It is known that, within the SM, the flavor-changing neutral current (FCNC) interactions are forbidden at tree level and are also highly suppressed at higher orders, due to the Glashow-Iliopoulos-Maiani mechanism [10].
To probe new physics, the anomalous flavor changing neutral current (FCNC) Yukawa interactions, between the top-Higgs and either an up or charm quark, would provide a clear signal.
Furthermore, a remarkable restriction over charged Higgs masses comes from Flavor Changing Neutral Current (FCNC), radiative B-meson decay, whose branching ratio BR (b [right arrow] s[gamma]) [approximately equal to] 3 x [10.sup.-4] [8] is measured with sufficient precision that becomes sensitive to new physics.
The flavor changing neutral current (FCNC) transitions of [[LAMBDA].sub.b] [right arrow] [LAMBDA][l.sup.+][l.sup.-], [[SIGMA].sub.b] [right arrow] [SIGMA][l.sup.+][l.sup.-], and [[XI].sub.b] [right arrow] [XI][l.sup.+][l.sup.-] are among important baryonic decay channels that can be used as sensitive probes to indirectly search for new physics contributions.
The anomalous interactions of the top quark can occur in various flavour-changing neutral current (FCNC) processes like t [right arrow] qX, where X = g, [gamma], Z, or Higgs.
