Theoretical Status of Pentaquarks [PDF]
, 2007 We review the current status of the theoretical pentaquark search from the direct QCD calculation. The works from the QCD sum rule and the lattice QCD in the literature are carefully examined.

International Journal of Modern Physics E, 2009 We prove that Nambu–Jona-Lasinio model is an exact description of infrared Quantum ChromoDynamics (QCD) deriving it from QCD Lagrangian. The model we obtain is renormalizable and confining but, taking very small momenta fixes completely all the parameters of the Nambu–Jona-Lasinio model through those of QCD.

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).

Instanton, Monopole Condensation and Confinement [PDF]
, 1997 The confinement mechanism in the nonperturbative QCD is studied in terms of topological excitation as QCD-monopoles and instantons. In the 't Hooft abelian gauge, QCD is reduced into an abelian gauge theory with monopoles, and the QCD vacuum can be ...

Hyperfine Interactions, 2014 QCD-motivated models for hadrons predict an assortment of "exotic" hadrons that have structures that are more complex then the quark-antiquark mesons and three-quark baryons of the original quark-parton model. These include pentaquark baryons, the six-quark H-dibaryon, and tetra-quark, hybrid, and glueball mesons.

Broadband tunable phase shifter for microwaves
AIP Advances, 2020 We implement a broadly tunable phase shifter for microwaves based on superconducting quantum interference devices (SQUIDs) and study it both experimentally and theoretically.

QCD Thermodynamics with 2 and 3 Quark Flavors [PDF]
, 2000 We discuss the flavor dependence of the pressure and critical temperature calculated in QCD with 2, 2+1 and 3 flavors using improved gauge and staggered fermion actions on lattices with temporal extent Nt=4.

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 ...

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.
