Hurst exponent and prediction based on weak-form efficient market hypothesis of stock markets
Cheoljun Eom, Sunghoon Choi, Gabjin Oh +1
We empirically investigated the relationships between the degree of efficiency and the predictability in financial time-series data. The Hurst exponent was used as the measurement…
Search for the Decay
E391a Collaboration, J. K. Ahn
We performed a search for the decay at the KEK 12-GeV proton synchrotron. No candidate events were observed. An upper limit on the branching ratio for the de…
Energy Dependence of Multiplicity Fluctuations in Heavy Ion Collisions at the CERN SPS
The NA49 Collaboration, B. Lungwitz
Multiplicity fluctuations of positively, negatively and all charged hadrons in the forward hemisphere were studied in central Pb+Pb collisions at 20A, 30A, 40A, 80A and 158A GeV. T…
High Transverse Momentum Hadron Spectra at sqrt{s_{NN}}=17.3 GeV, in Pb+Pb and p+p Collisions
NA49 Collaboration
Transverse momentum spectra up to 4.5 GeV/c around midrapidity of pi^{+/-}, p, pbar, K^{+/-} in Pb+Pb reactions were measured at sqrt{s_{NN}}=17.3 GeV by the CERN-NA49 experiment.…
The Electric Dipole Moment of the Nucleons in Holographic QCD
Deog Ki Hong, Hyun-Chul Kim, Sanjay Siwach +1
We introduce the strong CP-violation in the framework of AdS/QCD model and calculate the electric dipole moments of nucleons as well as the CP-violating pion-nucleon coupling. Our…
Pion and kaon production in central Pb+Pb collisions at 20A and 30A GeV: Evidence for the onset of deconfinement
NA49 Collaboration
Results on charged pion and kaon production in central Pb+Pb collisions at 20A and 30A GeV are presented and compared to data at lower and higher energies. A rapid change of the en…
