Vacuum Condensates in the Global Color Symmetry Model

, 1999
Based on the quark propagator in the instanton dilute liquid approximation, we calculate analytically the quark condensate $$, the mixed quark gluon condensate $g_{s}$ and the four quark condensate $$ at the mean field level in the framework of global ...

Unraveling the final-state interactions and correlations inside high-multiplicity jets at LHC [PDF]

EPJ Web of Conferences
Recent CMS measurements on high-multiplicity jets have revealed intriguing near-side long-range correlations in two-particle correlations within jets containing over 80 charged tracks.

RELATIVISTIC QUARK MODEL

Fizika B : a journal of experimental and theoretical physics, 1999
A general Lorentz-covariant quark model of mesons, whose nonrelativistic limit corresponds to Isgur-Scora-Grinstein-Wise model, is constructed. It possesses the heavy quark symmetry and can be easily applied to calculation of form factors. Besides it can be engaged in novel tasks, such a the investigation of the two photon decay of scalar mesons.

Generating the Critical Ising Model via SRGAN: A Schramm–Loewner Evolution Analysis from a Geometric Deep Learning Perspective

Entropy
The geometric signatures of macroscopic interfaces in the two-dimensional critical Ising model strictly adhere to Schramm–Loewner Evolution (SLE) theory.

Non-hydrodynamic response in QCD-like plasma

Journal of High Energy Physics
Quark-gluon plasma’s (QGP) properties at non-hydrodynamic and non-perturbative regimes remain largely unexplored. Here, we examine the response functions describing how a QGP-like plasma responds to initial energy-momentum disturbance in both static and ...

Dijet asymmetry in the resummation improved perturbative QCD approach

Physics Letters B, 2018
We develop the first systematic theoretical approach to dijet asymmetries in hadron–hadron collisions based on the perturbative QCD (pQCD) expansion and the Sudakov resummation formalism.

Internal multiplicity distributions of jets from nonlinear evolution within the jet function framework

Journal of High Energy Physics
Jets selected with high internal charged-particle multiplicity exhibit markedly different substructure patterns compared to inclusive jet samples.

Rare W → B c + γ decay up to the NNLO and NLL accuracy in QCD

Journal of High Energy Physics
We perform a detailed theoretical study of the rare radiative decay of the W boson into a B c meson and an on-shell photon. The decay amplitude is described by two independent form factors, which are calculated up to the next-to-next-to-leading order ...
