Vor 5 Tagen · If millicharged particles (MCPs) exist they can be created in the atmosphere when high energy cosmic rays collide with nuclei and could subsequently be detected at neutrino experiments. We extend previous work, which considered MCPs from decays of light mesons and proton bremsstrahlung, by including production from $Υ$ meson decays and the Drell-Yan process. MCPs with masses below a GeV ...
Vor 3 Tagen · He was replaced by Rudolf Peierls from the British Mission, who in turn brought in Klaus Fuchs, who was later revealed to be a Soviet spy. [44] [42] Teller's Super group became part of Fermi's F Division when he joined the Los Alamos Laboratory in September 1944. [44]

Vor 4 Tagen · I. INTRODUCTION. The existence of dark matter, along with current un-derstanding of the richness of typical string theory com-pactifications [1–3], motivates the presence of additional “dark” sectors that are only very weakly coupled to the Standard Model (SM).
Vor 2 Tagen · In the dark dimension scenario, which predicts an extra dimension of micron scale, dark gravitons (KK modes) are a natural dark matter candidate. In this paper, we study observable features of this model. In particular, their decay to standard matter fields can distort the CMB and impact other astrophysical signals. Using this we place bounds on the parameters of this model. In particular we ...
Vor 5 Tagen · Particle systems with Coulomb or Lennard-Jones interactions will serve as examples. The former decay as 1/r with the distance r between charged particles. Its long-range nature derives from the masslessness of the photon. The Lennard-Jones potential describes the interaction between uncharged, non-polar atom.
