style="font-family:"Times New
Roman",serif;mso-fareast-language:EN-US">We explore the
calculation of pion form factor at high momentum transfer.
The determinations of the spectrum of the pion is performed
on dynamical lattices with two volumes and with pion masses
heavier than twice the physical mass. We employ an
anisotropic lattice using a tree level improved clover quark
and gauge actions featuring two lighter degenerate flavors
of quarks, and a heavier quark tuned to approximate the
quark mass gap with the lightest two quarks. We utilize the
technology necessary to isolate a single matrix element via
the use of variationally optimized operators. This
exploratory calculation constitutes the very first
determination of the electromagnetic form factor of pion at
high momentum transfer within a first principle approach to
QCD performed using distillation framework to give a
quantitative picture, relevant to the experimental
measurements at Jefferson Lab. Focusing on two regimes where
the long distance or low momentum regime relevant for the
calculation of the charge radius and the short distance or
high momentum regime describing the approach to quark and
gluonic degrees of freedom. We find that our calculation
agree within a value below that of the vector meson
dominance pole form appropriate to low momentum transfer and
above that of the asymptotic perturbative QCD calculation at
high momentum transfer. Our calculations show that in
principle we can reach higher momentum transfer values by
implementing the method of momentum smearing in our quark
field design to further explore the region where the
perturbative QCD result emerges at higher momentum transfer.<o:p></o:p></span></p>

was born in Jakarta, Indonesia. His late father, a physics
professor, encouraged scientific inquiry. Since his youth
Adithia has always enjoyed studying science and philosophy.
He majored in Nuclear Physics at Pelita Harapan University
in Indonesia, receiving a full scholarship for his
undergraduate physics studies from the Surya Institute.
After completing his senior thesis on the topic of Monte
Carlo for radiation therapy dose calculations, he graduated
in January 2008 magna cum laude. For two years he worked as
an editor for high school physics textbooks.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Times New

entered College of William & Mary in Fall 2009. In 2011,
he joined Prof. Kostas Orginos' Lattice QCD group. His
research in the study of hadronic form factor at high
momentum transfer helps to link a non-perturbative QCD with
perturbative QCD. He and his wife Sasha met at church in
2014 and are expecting their firstborn son on Christmas Day.
After graduation, he hopes to continue in the field of
physics and instill a love of science in their children.</span><span
