Parallel Session T12: New theoretical developments
- Michał Praszałowicz (Instytut Fizyki Teoretycznej UJ)
We present some analytic results that describe the gluon field, or glasma, that exists at very early times after a collision of relativistic heavy ions at proper time $\tau=0$. We use a Colour Glass Condensate approach, and perform an expansion in $\tau$. We show that the expansion to order $\tau^6$ can be trusted to about $\tau=0.05$ fm/c. We calculate the transverse and longitudinal...
We explore the far-from-equilibrium dynamics of a (0+1)-dimensionally expanding system of massive particles with Bjorken symmetry using kinetic theory and hydrodynamics. By comparing the decay of various initializations on the attractor in both frameworks, we test the effectiveness of hydrodynamics in providing an accurate description of the underlying kinetic theory in far-off-equilibrium...
The fast development of quantum technologies over the last decades has offered a glimpse to a future where the quantum properties of multi-particle systems might be more fully understood. So far, quantum computing has seen ample application in areas such as quantum chemistry or condensed matter, but its usage in high energy physics is still in its infancy. In the particular case of QCD jets,...
Parton showers lie at the core of general purpose Monte Carlo event generators. They aim at correctly describing the phase-space for QCD branchings across disparate energy scales. A natural question, largely overlooked in the literature, is up to which degree of logarithmic accuracy do parton showers meet this goal. In this talk, I’ll present a new class of dipole showers for hadronic...
Collisional broadening in QCD plasmas leads to the emission of medium induced radiation, which governs the energy loss of highly energetic particles or jets. While recent studies have obtained non-perturbative contributions to the collisional broadening kernel $C(b_{\bot})$ using lattice simulation of the dimensionally reduced long-distance effective theory of QCD, Electrostatic QCD (EQCD)...
