Science, by nature, is the attempt to understand the world around you and be able to make predictions on how nature will behave. 
Earlier I mentioned how Newtonian Mechanics is to Relativity as the Standard Model is to Beyond the Standard Model and so it is 
only appropriate that what began with a quote from Newton is summed up by a quote from Einstein. In both cases, I must agree 
whole heartedly with their statements. Particle physics is not unique in going beyond the standard physics of everyday life and 
looking at something deeper but I do find it unique in how well defined and documented its history is. What we learn from papers 
now will be written down in books before too long and a lot of that has to do with how the field handles itself and propagates 
its own wavefunction forward in time. And so it is with this work.

Though our goals were not as lofty as grand unified theories, or even full extensions and replacements of the SM, our work does 
serve an important role in describing and predicting what may be seen in a corner of particle physics. The Higgs sector, as the 
newest sector to be discovered experimentally, still has much to provide us with in terms of information in how the Yukawa 
couplings work and why some particles are so much more massive than the other. Our research also shows, that it is possible and 
likely that this is one of the areas in which we will first see evidence of new physics. new physics, we define as physics beyond 
the SM. As Run II is wrapping up we hope some of the date may either math our predictions for flavor changing neutral currents 
or help further constrain the parameter space for future dedicated studies. Both the leptonic, \tamu, and the hadronic, $tc$, 
flavor changing interactions still have a fairly large parameter space in which the couplings might lie and the more we find out 
about this parameter space the more we will know about the alignment limit, \cosba, and the diagonal mass-based Yukawa couplings 
that are stored in the $\kappa$ matrices.

We acknowledge that it is also possible the general treatment of the Two Higgs Doublet Model is too generous and needs to be 
further constrained as in the Type-II model required by SUSY but we have no direct indications of that yet. We hope this 
study will help us gain some more insight. We will be finishing up the \tamu project soon after refining some of the data with 
higher fidelity information that we were not able to collect until now and studies into the $\rho_{tc}$ coupling will continue 
in the group going forward as there is a lot that can be done with the kenematically viable $t \to c h^0$ decay mode. Some 
preliminary work has already been completed and will, hopefully, be finished by the end of the calendar year.

Flavor changing neutral currents mediated by Higgs bosons are not the answer to all the questions the SM needs some help resolving, 
but they are a small step in a direction that can tell us a lot about how nature works. And to anyone who says particle physics is 
dead and there isn't anything left to find I simply say, look harder, the answers are there, we just need to find them.
