Critical dynamical fluctuations near the QCD critical point
He jishu, 2023 The exploration of the critical point on the QCD (Quantum Chromodynamics) phase diagram is one of the most important goals of the beam energy scan program in relativistic heavy-ion collisions (RHIC-BES).

QCD, supersymmetric QCD, lattice QCD and string theory: Synthesis on the horizon? [PDF]
Nuclear Physics B - Proceedings Supplements, 1999 Supersymmetric gauge theories in four dimensions have taught us many important physics lessons. These can both inform and be informed by future work on the lattice. I focus on three issues: the properties of supersymmetric Yang-Mills theory and its relation to the non-supersymmetric case; the properties of gauge theories with matter and their relation ...

Constraints on "Second Order Fixed Point" QCD from the CCFR Data on Deep Inelastic Neutrino-Nucleon Scattering [PDF]
, 1996 The results of LO {\it Fixed point} QCD (FP-QCD) analysis of the CCFR data for the nucleon structure function $~xF_3(x,Q^2)~$ are presented. The predictions of FP-QCD, in which the Callan-Symanzik $~\beta~$ function admits a {\it second order ...

Coloring mixed QCD/QED evolution
SciPost Physics, 2022 Parton showers are crucial components of high-energy physics calculations. Improving their modelling of QCD is an active research area since shower approximations are stumbling blocks for precision event generators.

Efficient protocol for qubit initialization with a tunable environment
npj Quantum Information, 2017 Quantum computers: Back to square zero The ability to accurately reset qubits is one of the fundamental criteria in implementing quantum computers. Jani Tuorila and co-workers from Aalto University (Finland) propose a qubit initialization protocol using ...

QCD Dirac operator at nonzero chemical potential: lattice data and matrix model [PDF]
, 2003 Recently, a non-Hermitian chiral random matrix model was proposed to describe the eigenvalues of the QCD Dirac operator at nonzero chemical potential. This matrix model can be constructed from QCD by mapping it to an equivalent matrix model which has ...

Deep Inelastic Scattering, 2002 A review on how the Odderon idea does appear in QCD is given. In the last years it has been developed a non-perturbative QCD approach based on the stochastic vacuum model and a perturbative one based on resummation techniques in the small x QCD region.

Universe, 2019 The temperature (T) dependence of the axion mass is predicted for T ′ s up to ∼ 2.3 × the chiral restoration temperature of QCD. The axion is related to the U A ( 1 ) anomaly. The squared axion mass m a
