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 ...

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 ...

This monumental collection of thirty-four historical papers on quantum electrodynamics features contributions from the twentieth century's leading physicists: Dyson, Fermi, Feynman, Foley, Heisenberg, ...

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 ...

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 ...

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 ...

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 ...

Muon tomography, based on the measurement of multiple scattering of cosmic ray muons traversing a volume to be investigated, is an attractive technique for detecting hidden high-Z materials. A cosmic ...
