NYCU HEP seminar

[Valentin Moos]

Dear colleagues,

I want to announce our next HEP seminar
for tomorrow, Tuesday, 5th of May:

Speaker: Hsiang-Nan Li (Academia Sinica)
Title:  Subleading contributions to Single Spin Asymmetries in SIDIS and DY

Below you can find the abstract for the talk:
"We explain the mechanism for generating transverse single-spin
asymmetry (SSA) in a fundamental point of view, based on which
relevant transverse-momentum-dependent distribution functions
are introduced up to two-loop and twist-three level. We then
quantitatively investigate the new contributions from the gT(x)
distribution to transverse SSAs in semi-inclusive deep inelastic
scattering and Drell-Yan processes. It is shown that the
asymmetries can reach percent-level magnitude, if the kinematics
predominantly probes the large-x (valence) region of the polarized
proton."

With this email, we want to kindly invite everyone who is interested.

Dear all,
Dear colleagues,
this is an announcement for the HEP seminar at NYCU tomorrow, 2:20 pm.

Speaker: Alberto Ramos (Universitat de Valencia, Spain)
Title:  The strength of the interaction between quarks
  and gluons

Below you can find the abstract for the talk:

"Modern particle physics experiments, e.g. at the Large Hadron Collider
(LHC) at CERN, crucially depend on the precise description of the
scattering processes in terms of the known fundamental forces. This is
limited by our current understanding of the strong nuclear
force. Relating the coupling between the fundamental quarks and gluons
to experiments poses a major challenge as the strong interactions lead
to the confinement of quarks and gluons inside hadronic bound states. At
high energies, however, the strong interactions become weaker
("asymptotic freedom") and thus amenable to an expansion in powers of
the coupling. Attempts to relate both regimes usually rely on modeling
of the bound state problem in one way or another. I will show how large
scale numerical simulations of a first principles formulation of Quantum
Chromodynamics on a space-time lattice allows to determine the strength
of the strong nuclear force without any need to model the confinement of
quarks.  "

Everyone is invited to attend!

Dear colleagues,

This is the announcement for our next HEP seminar
at NYCU on next Tuesday, 20th of May:

Speaker: Alex Chang (NYCU)
Title:   Parton Physics from a Heavy-quark Operator Product Expansion: Lattice QCD Calculation of the First and Second Moment of the Kaon Distribution Amplitude

Below you can find the abstract for the talk:

" The kaon light-cone distribution amplitude (LCDA) is a crucial quantity in understanding the structure of hadrons. In this work, we use lattice quantum chromodynamics (LQCD), a powerful tool for calculating non-perturbative quantities. Since LQCD calculations are performed in Euclidean space, we apply the heavy-quark operator product expansion (HOPE) to connect light-cone parton dynamics with calculations in Euclidean space. This approach entails an OPE analysis of hadronic amplitudes in Euclidean space through the insertion of two local quark bilinears with a fictitious, valence heavy quark. We present the status of our numerical calculation for the first and second Mellin moments of the kaon LCDA obtained through the HOPE framework, advancing our understanding of parton distributions in mesons. "

With this email, we kindly invite anyone interested to attend.
