Strongly-interacting Heavy Flavors beyond the Standard Model A
The origin of mass must lie in physics beyond the Standard Model. Dynamical electroweak symmetry breaking models like technicolor can generate masses for the W and Z bosons. Providing the large top quark mass and large top-bottom mass splitting while keeping ∆ρ and flavor-changing neutral currents small requires new strong dynamics for the top and bottom quarks. In consequence, new particles ar...
متن کاملHeavy baryon mass spectrum from lattice QCD with 2+1 dynamical sea quark flavors
We investigate the mass differences of charm and bottom heavy baryons, using MILC lattice gauge configurations with 2+1 dynamical sea quark flavors. We extend our previous work to three lattice spacings: fine (a≈ 0.09), coarse (a≈ 0.12), and medium-coarse (a≈ 0.15) ensembles. For extrapolations and interpolations, we apply simultaneous quadratic fits and simple linear fits with the full QCD dat...
متن کاملLattice QCD with Eight Degenerate Quark Flavors
We report on simulations of QCD with many flavors of degenerate quarks, the DBW2 gauge action and naive staggered fermions, using the rational hybrid Monte Carlo algorithm. We primarily focus on eight degenerate quark flavors where a variety of values of the coupling constant and quark mass have been used in the simulations. The scaling behavior of the hadron spectrum and the string tension of ...
متن کاملDileptons from the strongly interacting quark-gluon plasma (sQGP)
To address the dilepton production in a hot and dense medium – as created in heavy-ion collisions – we employ an up-to-date relativistic transport model, i.e. the Parton Hadron String Dynamics [1] (PHSD) that incorporates the explicit partonic phase in the early reaction region. The approach consistently describes the full evolution of a relativistic heavy-ion collision from the initial hard sc...
متن کاملA ug 2 00 2 1 Jet Quenching with Detailed Balance in a Thermal QCD Medium ∗
The effect of detailed balance in induced gluon radiation for an energetic parton propagating inside a quark-gluon plasma is discussed. The stimulated thermal gluon emission reduces while absorption increases the parton's energy. The net contribution results in a reduction of the effective parton energy loss. The relative reduction of the parton energy loss is found to be important for intermed...
