A Colorful Wake for Gerhard Soff
نویسندگان
چکیده
Abstract. We calculate the wake induced in a hot QCD plasma by a fast parton in the framework of linear response theory. We discuss two scenarios: (i) a weakly coupled quark-gluon plasma described by hard-thermal loop perturbation theory and (ii) a strongly coupled quark-gluon plasma which resembles a quantum liquid. We show that a Mach cone can appear in the second scenario, but not in the first one.

متن کاملQuasi-particle model of strongly interacting matter
The successful quasi-particle model is compared with recent lattice data of the coefficients in the Taylor series expansion of the excess pressure at finite temperature and baryon density. A chain of approximations, starting from QCD to arrive at the model expressions for the entropy density, is presented.

The theory of direct electron-positron pair production in the collision of heavy ions i s formulated in the framework of the quasimolecular model. The pair production process acquires a collective nature for (Z1 +Z,)cu; 1 and can be understood a s the shakeoff of the strong vacuum polarization cloud formed in the quasimolecule. The total Cross section is, e .g., 76 l b for Pb + Pb at Coulomb ba...
متن کاملPresynaptic calcium dynamics of learning neurons
We present a new model for the dynamics of the presynaptic intracellular calcium concentration in neurons evoked by various stimulation protocols. The aim of the model is twofold: We want to discuss the calcium transients during and after specific stimulation protocols as they are used to induce longterm-depression and long-term-potentiation. In addition we would like to provide a general tool ...
متن کاملHelicity Formalism for Spin - 2 Particles ∗
We develop the helicity formalism for spin-2 particles and apply it to the case of gravity in flat extra dimensions. We then implement the large extra dimensions scenario of Arkani-Hamed, Dimopoulos and Dvali in the program AMEGIC++, allowing for an easy calculation of arbitrary processes involving the emission or exchange of gravitons. We complete the set of Feynman rules derived by Han, Lykke...
