ALICE makes first direct observation of a fundamental effect in particle physics（图）
ALICE particle physics fundamental effect charm quark
2022/6/27
The ALICE collaboration at the Large Hadron Collider (LHC) has made the first direct observation of the dead-cone effect – a fundamental feature of the theory of the strong force that binds quarks and...

Effect of three-pion unitarity on resonance poles from heavy meson decays 。
The effect of higher derivative correction on $η/s$ and conductivities in STU model
higher derivative conductivities in STU model
2010/12/23
In this paper we study the ratio of shear viscosity to entropy, electrical and thermal conductivities for the R-charged black hole in STU model. We generalize previous works to the case of a black hol...
Observational constraints on Chaplygin cosmology in a braneworld scenario with induced gravity and curvature effect
Observational constraints Chaplygin cosmology braneworld scenario
2010/12/27
We study cosmological dynamics and late-time evolution of an extended induced gravity braneworld scenario. In this scenario, curvature effects are taken into account via the Gauss-Bonnet term in the ...
Dark Matter as a Relativistic Inertial Effect in Einstein Canonical Gravity?
Dark Matter Relativistic Inertial Effect Einstein Canonical Gravity
2010/12/27
After the study of non-inertial frames in special relativity with emphasis on the problem of clock synchronization (i.e. of how to define 3-space), an overview is given of Einstein canonical gravity ...
The Chiral Magnetic Effect and chiral symmetry breaking in SU(3) quenched lattice gauge theory
The Chiral Magnetic Effect chiral symmetry breaking
2011/1/7
We study some properties of the non-Abelian vacuum induced by strong external magnetic field. We perform calculations in the quenched SU(3) lattice gauge theory with tadpole-improved Luscher-Weisz act...
Energy and system-size dependence of the Chiral Magnetic Effect
Energy system-size dependence the Chiral Magnetic Effect
2010/12/29
The energy dependence of the local ${\cal P}$ and ${\cal CP}$ violation in Au+Au and Cu+Cu collisions in a large energy range is estimated within a simple phenomenological model. It is expected that a...
Spin precession and modulation in ballistic cylindrical nanowires due to the Rashba effect
Spin precession ballistic cylindrical nanowires
2010/11/24
The spin precession in a cylindrical semiconductor nanowire due to Rashba spin-orbit coupling has been investigated theoretically using an InAs nanowire containing a surface two-dimensional electron g...
Tkachenko modes in rotating neutron stars: the effect of compressibility and implications for pulsar timing noise
Tkachenko modes rotating neutron stars effect of compressibility implications pulsar timing noise
2010/12/21
Long wavelength oscillations (Tkachenko waves) of the triangular lattice of quantized vortices in super uid neutron stars have been suggested as one of the possible explanations for the timing noise o...
We present data on the modulation of the dark port power at the free spectral range frequency of the LIGO 4 km interferometers. It is found that the power is modulated exactly at the tidal frequencies...
Effect of current quark masses on quark phase transitions in supernovae
quark phase transition current quark mass supernova
2009/8/14
The current quark mass model is adopted to study the phase transition of two-flavor quark matter to more stable three-flavor quark matter in the whole core of a supernova. It shows that the timescale ...
Single particle properties in asymmetric nuclear matter and TBF rearrangement effect
asymmetric nuclear matter single particle properties Brueckner theory three-body force rearrangement effect
2009/8/14
We have developed the formula and the numerical code for calculating the rearrangement contribution to the single particle (s.p.) properties in asymmetric nuclear matter induced by three-body forces ...
Electrodynamic Casimir Effect in a Medium-Filled Wedge
Electrodynamic Casimir Effect Medium-Filled Wedge
2010/4/9
We re-examine the electrodynamic Casimir effect in a wedge defined by two perfect conductors making dihedral angle \alpha=\pi/p. This system is analogous to the system defined by a cosmic string. We c...
