Title : Form factors on the lattice

Abstract : 
The quark flavor sector of the Standard Model is a fertile ground to test any new physics effect through the Unitarity test of the Cabbibo-Kobayashi-Maskawa (CKM) matrix. Therefore, I present a lattice QCD calculation of the scalar and the vector form factors (over the full physical q^2 region including q^2=0) associated with the D to K meson semi-leptonic decay. The central CKM matrix element, V_{cs} in the Standard Model, is then calculated by comparing the lattice QCD results for the form factors and the experimental decay rate. 

In the second part of my talk, I present a lattice calculation of the pion electromagnetic form factor at up to q^2~6.0 GeV^2. This is a fundamentally important topic for our understanding of the hadron structure, the transition from perturbative to nonperturbative QCD, and to compare with JLAB’s experiment E12-06-101 which proposes to extend the high quality pion form factor data to Q^2>6.0 GeV^2.


Dear all,
tomorrow there will be a Cake Seminar.
Bipasha Chakraborty will report on his research activities and give a talk
about "Form factors on the lattice".
Please, let us know if you are not onsite and you would like to follow
the talk remotely. We can set up a bluejeans connection.

Yours sincerely,

Alessandro, Andrea, Bipasha.
