Spin Physics through QCD Instantons
Yachao Qian, Ismail Zahed
We review some aspects of spin physics where QCD instantons play an important role. In particular, their large contributions in semi-inclusive deep-inelastic scattering and polariz…
Streched String with Self-Interaction at the Hagedorn Point: Spatial Sizes and Black Hole
Yachao Qian, Ismail Zahed
We analyze the length, mass and spatial distribution of a discretized transverse string in dimensions with fixed end-points near its Hagedorn temperature. We suggest that…
Stretched String with Self-Interaction at High Resolution: Spatial Sizes and Saturation
Yachao Qian, Ismail Zahed
We model the (holographic) QCD Pomeron as a long and stretched (fixed impact parameter) transverse quantum string in flat dimensions. After discretizing the string in $…
Double Spin Asymmetries through QCD Instantons
Yachao Qian, Ismail Zahed
We revisit the large instanton contribution to the gluon Pauli form factor of the constituent quark noted by Kochelev. We check that it contributes sizably to the single spin asymm…
Stringy Pomeron: Entropy and Shear Viscosity
Yachao Qian, Ismail Zahed
We model the soft pomeron contribution to dipole-dipole scattering as a closed string exchange in AdS5 with a wall. The exchange of closed and long strings is characterized by an a…
P-Odd Pion Azimuthal Charge Correlations in Heavy Ion Collisions
Yachao Qian, Ismail Zahed
We argue that the large instanton induced Pauli form factor in polarized proton-proton scattering may cause, through topological fluctuations, substantial charge-dependent azimutha…
Single Spin Asymmetry through QCD Instantons
Yachao Qian, Ismail Zahed
We revisit the effects of QCD instantons in semi-inclusive deep inelastic scattering (SIDIS). We show that large single spin asymmetry (SSA) effects can be induced in longitudinall…
