Doubly charmed baryon production in heavy ion collisions
Xiaojun Yao, Berndt Müller
We give an estimate of production rate and transverse momentum spectra in relativistic heavy ion collisions. We use Boltzmann transport equations to describe the dyna…
Almost exponential transverse spectra from power law spectra
Tamas S. Biro, Berndt Muller
We point out that exponential shape of transverse spectra can be obtained as the Fourier transform of the limiting distribution of randomly positioned partons with power law spectr…
Nuclear Enhanced Higher-Twist Effects in the Drell-Yan Process
R. J. Fries, A. Schäfer, E. Stein +1
We calculate the Drell-Yan cross section, resolving the full kinematics of the lepton pair, at high transverse momentum for hadron nucleus collisions. We use the general framework…
Angular Dependence of the Nuclear Enhancement of Drell-Yan Pairs
R. J. Fries, B. Müller, A. Schäfer +1
We calculate the nuclear enhancement in the angular distribution of Drell-Yan pairs produced in proton-nucleus reactions. Nuclear effects are encoded in universal twist-4 parton co…
Anomaly Induced Domain Formation of Disoriented Chiral Condensates
M. Asakawa, H. Minakata, B. Muller
We discuss the effect of chiral anomaly as a possible mechanism for triggering formation of domains of disoriented chiral condensate (DCC) in relativistic heavy ion collisions. The…
Chern-Simons number diffusion with hard thermal loops
Guy D. Moore, Chaoran Hu, Berndt Muller
We construct an extension of the standard Kogut-Susskind lattice model for classical 3+1 dimensional Yang-Mills theory, in which ``classical particle'' degrees of freedom are added…
Classical Lattice Gauge Fields with Hard Thermal Loops
C. R. Hu, B. Muller
We propose a formulation of the long-distance dynamics of gauge theories at finite temperature on a lattice in Minkowski space, including the effects of hard thermal loops on the d…
Chemical Equilibration of an Expanding Quark-Gluon Plasma
Dinesh Kumar Srivastava, Munshi Golam Mustafa, Berndt Müller
The chemical equilibration of the parton distribution in collisions of two heavy nuclei at the CERN Large Hadron Collider is investigated. Initial conditions are obtained from a se…
Symmetry Restoration in Gauge Boson Wave Packet Collisions in Yang-Mills-Higgs Theory
C. R. Hu, S. Matinyan, B. Muller
We investigate the restoration of spontaneously broken gauge symmetry in collisions of gauge boson wave packets in the SU(2) Higgs model.
The Search for the Quark-Gluon Plasma
John W. Harris, Berndt Müller
We provide an overview of the present understanding of the transition from hadrons to a quark-gluon plasma, its signatures, and the experimental results so far. We discuss results…
Wave Packet Collisions in Yang-Mills-Higgs Theory
C. R. Hu, S. G. Matinyan, B. Muller +1
We present numerical simulations of colliding wave packets in spontaneously broken SU(2) Yang-Mills-Higgs theory. Compared with pure Yang-Mills theory, introducing the Higgs field…
Chaos Driven by Soft-Hard Mode Coupling in Thermal Yang-Mills Theory
T. S. Biro, S. G. Matinyan, B. Muller
We argue on a basis of a simple few mode model of SU(2) Yang-Mills theory that the color off-diagonal coupling of the soft plasmon to hard thermal excitations of the gauge field dr…
Wavepacket Dynamics in Yang-Mills Theory
C. Hu, S. Matinyan, B. Muller +4
We discuss the results of numerical simulations of colliding wavepackets in Yang--Mills theory. We investigate their behavior as a function of amplitude and momentum distri…
Pion Fusion in Peripheral Collisions
Alec J. Schramm, Berndt Müller
We estimate the cross section for quasi-elastic double pion exchange in high energy proton-proton collisions. Total and elastic cross sections are calculated in an equivalent…
Lyapunov Exponent and Plasmon Damping Rate in Nonabelian Gauge Theories
T. S. Biro, C. Gong, B. Mueller
We explain why the maximal positive Lyapunov exponent of classical SU() gauge theory coincides with (twice) the damping rate of a plasmon at rest in the leading order of thermal…
Larger Domains of Disoriented Chiral Condensate Through Annealing
Sean Gavin, Berndt Mueller
Relativistic heavy ion collisions can generate metastable domains in which the chiral condensate is disoriented. Nucleus-sized domains can yield measurable fluctuations in the numb…
QCD Evolution Equations for High Energy Partons in Nuclear Matter
Klaus Geiger, Berndt Mueller
We derive a generalized form of Altarelli-Parisi equations to decribe the time evolution of parton distributions in a nuclear medium. In the framework of the leading logarithmic ap…
Some remarks on pion condensation in relativistic heavy ion collisions
C. Greiner, C. Gong, B. Müller
Recently it was pointed out that coherent or condensated states of pions may account for the explanation of the Centauro events observed in cosmic ray showers. We argue that an occ…
