System size dependence of intermediate mass fragments in heavy-ion collisions
heavy-ion collisions intermediate mass fragments
2011/7/20
We simulate the central reactions of $^{20}$Ne+$^{20}$Ne, $^{40}$Ar+$^{45}$Sc, $^{58}$Ni+$^{58}$Ni, $^{86}$Kr+$^{93}$Nb, $^{129}$Xe+$^{118}$Sn, $^{86}$Kr+$^{197}$Au and $^{197}$Au+$^{197}$Au at differ...

Spectral properties quarks above Tc -- thermal mass
2011/1/6
Spectral properties of quarks above the critical temperature for deconfinement are analyzed in quenched lattice QCD on lattices of size 128^3x16. We study quark spectral function in energy and momentu...

Mass matrices of twice four families of quarks and leptons, scalars and gauge fields as predicted by the ''spin-charge-family-theory''
Mass matrices scalars spin-charge-family-theory
2010/12/27
The theory unifying spin and charges and predicting families, proposed as a new way to explain the assumptions of the standard model of the electroweak and colour interactions, predicts at the low ene...
Strange Quark Mass and $1^{++}$ Nonet Singlet-Octet Mixing Angle
Strange Quark Mass $1^{++}$ Nonet Singlet-Octet Mixing Angle
2011/1/7
We compute the strange quark mass from the analysis of the $f_1(1420)-f_1(1285)$ mass difference QCD sum rule, where the operator-product-expansion series is up to dimension six and to ${\cal O}(\alph...
OPE, Heavy-Quark Mass, and Heavy-Meson Decay Constants from QCD Sum Rules
OPE Heavy-Quark Mass Heavy-Meson Decay Constants
2011/1/7
We present a sum-rule extraction of the decay constants of heavy-light mesons from the two-point correlator of pseudoscalar currents. To this end, we compare the perturbative expansions for the correl...
The order of the deconfinement phase transition in a heavy quark mass region
the deconfinement phase transition quark mass region
2011/1/7
We study the quark mass dependence of the QCD phase transition by an effective potential defined through the distribution function of observables. As a test of the method, we study the first order dec...
HIFLUGCS: Galaxy cluster scaling relations between X-ray luminosity, gas mass, cluster radius, and velocity dispersion
Cosmology observations (Cosmology:) dark matter Galaxies clusters
2011/1/5
We present relations between X-ray luminosity and velocity dispersion (L − ), X-ray luminosity and gas mass (L − Mgas), and cluster radius and velocity dispersion (r500 − ) for 62 ...
Non-perturbative renormalization of quark mass in Nf=2+1 QCD with the Schroedinger functional scheme
Non-perturbative renormalization quark mass in Nf=2+1 QCD
2011/1/6
We present an evaluation of the quark mass renormalization factor for Nf=2+1 QCD. The Schroedinger functional scheme is employed as the intermediate scheme to carry out non-perturbative running from t...
The Matrix Element Method and its Application in Measurements of the Top Quark Mass
Matrix Element Method Top Quark Mass
2010/3/16
The most precise measurements of the top quark mass are based on the Matrix Element method, which is designed to minimize the statistical uncertainty. We present a detailed description of this analysi...
The experimental status of measurements of the top quark mass is reviewed. After an introduction to the definition of the top quark mass and the production and decay of top quarks, an in-depth compari...
Center-of-Mass Correction in a Relativistic Hartree Approximation
Peierls-Yoccoz projection method Center-of-mass correction
2010/10/13
We use the Peierls-Yoccoz projection method to evaluate the center-of-mass correction of a relativistic system of nucleons and sigma and omega mesons, described in a mean-field Hartree approach. This ...
