We present a semianalytic technique for determining the complex normal-mode frequencies of black holes. The method makes use of the WKB approximation, carried to third order beyond the eikonal ...

LHAASO (Large High Altitude Air Shower Observatory) has provided crucial insights into the origin and nature of cosmic rays, particularly in the ultra-high-energy regime. Its results also have ...

We propose a description of the vacuum in Yang-Mills theory and arrive at a physical interpretation of the pseudoparticle solution and the attendant violation of symmetries. The existence of ...

The requirement that P and T be approximately conserved in the color gauge theory of strong interactions without arbitrary adjustment of parameters is analyzed. Several possibilities are identified, ...

The search for the decay μ + → e + e + e − with the SINDRUM spectrometer has been continued. The result is a new upper limit for the branching ratio B μ→3 e = Γ(μ→3 e ) Γ(μ→ e 2ν) < 1.0 × 10 −12 (90% ...

We propose new mechanisms for understanding neutrino masses in superstring models that contain E6-singlet zero-mass fields after compactification. We show that the low-energy gauge group of these ...

Using the data on deep inelastic muon scattering on iron and deuterium the ratio of the nucleon structure functions F 2 N ( Fe )/ F 2 N ( D ) is presented. The observed x -dependence of this ratio is ...

Total fission cross section induced by protons in ^181Ta and ^208Pb at energies in the range of 300 to 1000 A MeV have been measured at GSI (Germany) using the inverse kinematics technique. A ...

We study N=∞ lattice gauge theory at finite temperature by Monte Carlo methods using an asymmetric coupling version of the twisted Equchi-Kawai model. The data favor a first-order deconfining ...

We present a search for CP violation in single top quark production with the DØ experiment at the Tevatron proton-antiproton collider. CP violation in the top electroweak interaction results in ...

The WIMP limit set by the Xenon10 experiment in 2007 signals a new era in direct detection of dark matter, with several large-scale liquid target detectors now under construction. A major challenge in ...

If high energy heavy ion collisions lead to the formation of a hot quark-gluon plasma, then colour screening prevents cc binding in the deconfined interior of the interaction region. To study this ...
