Anomalous Transverse Distribution of Pions as a signal for the production of DCC ’ s

نویسنده

چکیده

We give evidence that the production of DCC’s during a nonequilibrium phase transition can lead to an anomalous transverse distribution of secondary pions when compared to a more conventional boost invariant hydrodynamic flow in local thermal equilibrium. Our results pertain to the linear σ model,treated in leading order in largeN , in a boost invariant approximation. We also show that the interpolating number density of the field theory calculation plays the role of a classical relativistic phase space number distribution in determining the momentum distribution of pions in the center of mass frame.

Coherence effects on pion spectrum distribution

The effects of two kinds of coherent lengths, the wave packet length of the emitter and the radius of the coherent source, on pion spectrum distribution are studied. It is shown that both coherent lengths can cause abundant pions at low momentum, but the DCC size effects on pion spectrum distribution is more important. So observing abundant pions at low momentum may be taken as a signal of DCC ...

Negative Elliptic Flow from Anomaly Induced DCC Formation

We discuss characteristic experimental signatures related to the mechanism of DCC formation triggered by the chiral U(1) anomaly in relativistic heavy ion collisions. We predict an enhancement of the fraction of neutral pions compared with all pions in the direction perpendicular to the scattering plane. To quantify the effect on the angular distribution of neutral pions, we compute the ellipti...

Dynamical simulation of DCC formation in Bjorken rods ∗

Using a semi-classical treatment of the linear σ model, we simulate the dynamical evolution of an initially hot cylindrical rod endowed with a longitudinal Bjorken scaling expansion (a " Bjorken rod "). The field equation is propagated until full decoupling has occurred and the asymptotic many-body state of free pions is then obtained by a suitable Fourier decomposition of the field and a subse...

Independent domains of disoriented chiral dondensate

The probability distribution of a neutral pion fraction from independent domains of disoriented chiral condensate is characterized. The signal for the condensate is still clear for a large number of independent domains if one of them is predominant. Typeset using REVTEX 1 A disoriented dhiral condensate (DCC) may be formed in large hot regions of hadronic matter where the approximate chiral sym...
