The possible existence of hybrid stars is studied using several multi-quark interaction channels. hadronic phase consists an equation state (EoS) with presently accepted nuclear matter properties and the quark model constrained by vacuum light mesons. dependence NS on different interactions analyzed. We show that present constraints from neutron star observations allow for large strangeness con...

We discuss the theory of jet events in high-energy photon-proton interactions using a model which gives a good description of the data available on total inelastic γp cross sections up to √ s=210 GeV. We show how to calculate the jet cross sections and jet multiplicities and give predictions for these quantities for energies appropriate for experiments at the HERA ep collider and for very high ...

In understanding the world of matter the introduction of symmetry principles following experimentation or using the predictive power of symmetry principles to guide experimentation is most profound. The conservation of energy, linear momentum, angular momentum, charge, and CPT involve fundamental symmetries. All other conservation laws are valid within a restricted subspace of the four interact...

Much of the energy of the nuclei colliding at RHIC or SPS is converted into final state hadronic particles. About a quarter of this energy is in baryons and antibaryons. There are nearly 10 strange quark pairs per central rapidity participant. Do we really understand the hadronic particle yields? Do we need to introduce post-Fermi-model ideas such as chemical non-equilibrium in order to underst...

We present a systematic way to combine the global color model and the instanton liquid model to calculate the chiral Lagrangian coefficients. Our numerical results are in agreement well with the experimental values. Quantum chromodynamics (QCD) is successful to describe strong interaction in terms of basic force at high energy. However, the large coupling constant at low energy makes the pertur...

Because the tau is the heaviest of the three leptons, specific final states involving taus are expected to show up in the Standard Model (SM), and would appear abundantly in many processes arising from new physics beyond the SM. Because taus decay to hadronic final states in about 64% of the cases, the reconstruction and identification of these hadronic decays is an essential ingredient of the ...

In this series of lectures, I shall begin with the current investigations on phenomenology of hadron dynamics to demonstrate the importance of solving hadronic bound states within the framework of light-front (LF) QCD. Then, I will describe the basic procedure how to formulate the canonical theory of LFQCD, including lightfront quantization of QCD, light-front gauge singularity, and light-front...
