Prompt publication of brief reports of important discoveries in physics may be secured by addressing them to this department. Closing dates for this department are, for the first issue of the month, tke eighteenth of the preceding month, for the second issue, the tkird of the month. Because of the late closing dates for the section no proof can be shown to authors. The Board of Editors does not hold itself responsible for the opinions expressed by the correspondents.

Heavy Electrons in Cosmic Rays
Neddermeyer and Anderson1, on the basis of their experiments on the loss of energy by cosmic ray particles, have suggested that there are present in cosmic rays ‘new’ particles of mass greater thanExpand
Nature of the Nuclear Field
AN attempt to explain neutron-proton interaction made by Yukawa1 in 1935 has been brought to general notice2,3 in connexion with the new experimental evidence for the existence of a ‘heavyExpand
Measurement of the Muon Lifetime
The only fundamental constituents of matter that are important for most of science are electrons, protons, and neutrons. It was thus a surprise when Carl D. Anderson and his student, Seth H.Expand
The Discovery of the Muon and the Failed Revolution against Quantum Electrodynamics
When was the muon discovered? According to G. Bernardini, “the mu meson as a peculiar ionizing fraction of the bulk of cosmic rays was revealed by an experiment by Bothe and Kolhcrster in 1929.”’Expand
Exclusive Scattering off the Deuteron
Exclusive processes are a special class of processes giving insight into the inner structure of hadrons. In this thesis we consider two exclusive processes and compute their total cross sections asExpand
Particle physics models with four generations
In this thesis we consider extending the standard model of particle physics (SM) to include a fourth generation of elementary particles (SM4). The fourth generation would have to be sufficientlyExpand
Searches for Scharms and Gluinos with the ATLAS Detector
Following the extremely successful operation of the Large Hadron Collider at CERN during its first years of operation, the ATLAS and CMS collaborations announced the discovery of a new particleExpand
Interplay between Yukawa and Tomonaga in the Birth of Mesons
Abstract Light is shed on the early stage in the birth of Yukawa's meson theory, particularly on the interplay between Yukawa and Tomonaga in 1933. The discovery of the muon by Nishina' group in 1937Expand
Muon Physics : A Pillar of the Standard Model( Frontiers of Elementary Particle Physics, the Standard Model and Beyond)
Since its discovery in the 1930s, the muon has played an important role in our quest to understand the sub-atomic theory of matter. The muon was the first second-generation standard-model particle toExpand
A Theory of the Muon; Explaining the Electron's Embarrassing Fat Cousin!
A theory of the muon is presented that explains the mass of the muon from a formula derived from the relativistic wave equations independently discovered by Lanczos, Weyl, and Van der Waarden usingExpand
