中国科学院“东方”超级计算系统助力格点QCD研究（图）
东方超级计算系统 量子色动力学
2022/10/28
“东方”超级计算系统是中国科学院新一代超级计算机。基于该系统的强大算力，LPC合作组完成了最大3亿格点数的大规模模拟计算，为量子多体问题中高能物理实验密切关注的物理量作出第一性原理预言提供了证实数据。
The talk, based on [1], analyzes the consequences of the assumption that the effects of quantum coherence and the resulting angular ordering in QCD cascades are disrupted within the hot fireball creat...
QCD under magnetic field: chiral magnetic effect at heavy ion collisions
chiral-magnetic e ect vector-current correlation charge separation
2011/1/10
In this talk, we report our recent studies for the chiral magnetic e ect, which signals the P- and CP-violations at heavy ion collisions. We compute the electric current and its correlations, induced ...
Lattice QCD at the physical point: light quark masses
Lattice QCD physical point light quark masses
2011/1/7
Ordinary matter is described by six fundamental parameters: three couplings (gravitational,
electromagnetic and strong) and three masses: the electron’s (me) and those of the up (mu)
and down (md) q...
OPE, Heavy-Quark Mass, and Heavy-Meson Decay Constants from QCD Sum Rules
OPE Heavy-Quark Mass Heavy-Meson Decay Constants from QCD Sum Rules
2011/1/7
We present a sum-rule extraction of the decay constants of heavy-lightmesons from the two-point
correlator of pseudoscalar currents [1]. To this end, we compare the perturbative expansions for the co...
Wave Functions of the Proton Ground State in the Presence of a Uniform Background Magnetic Field in Lattice QCD
Wave Functions of the Proton Ground State Uniform Background Magnetic Field
2011/1/13
We calculate the probability distributions of quarks in the ground state of the proton, and how
they are a ected in the presence of a constant background magnetic eld. We focus on wave functions in ...

We present the results of the recent high precision lattice calculation of the average up/down,
strange and charm quarkmasses performed by ETMC with Nf =2 twisted massWilson fermions.
The analysis i...
Non-linear QCD dynamics and exclusive production
Non-linear QCD dynamics exclusive production
2011/1/5
In this contribution we analyse the cross sections for the exclusive vector meson production as
well as the deeply virtual Compton scattering (DVCS) relying on the color dipole approach and
consider...
The aim of these lectures is to provide students with an introduction to some of the core concepts and methods of QCD that are relevant in an LHC context.
With the energy scales opened up by Rhic and Lhc the age of high-pT physics is upon us. This has created new opportunities and novel mysteries, both of which will be explored in this thesis. The possi...
Bosonic string behavior in UV filtered QCD
Bosonic Strings Finite temperature QCD Flux tubes
2011/1/13
The quark–antiquark potential and the gluonic action-density are calculated on sets of smeared gauge-field configurations at finite temperature just below the deconfinement temperature.
QCD, monopoles on the Lattice and gauge invariance
QCD Lattice Monopoles Color confinement
2011/1/13
The number and the location of the monopoles observed on the lattice in QCD configurations happens to depend strongly on the choice of the gauge used to expose them, in contrast to the physical expect...

2011/1/7
We present a sum-rule extraction of decay constants of heavy mesons from the two-point correlator of heavy-light pseudoscalar currents.
Comparison of the mass preconditioned HMC and the DD-HMC algorithm for two-flavour QCD
Comparison mass preconditioned HMC DD-HMC algorithm two-flavour QCD
2011/1/13
Mass preconditioned HMC and DD-HMC are among the most popular algorithms to simulate Wilson fermions. We present a comparison of the performance of the two algorithms for realistic
