Positronium Decay into a Photon and Neutrinos

Andrzej Pokraka, Andrzej Czarnecki

We determine the rates and energy and angular distributions of the positronium decays into a photon and a neutrino-antineutrino pair, Ps-->gamma+nu+anti-nu. We find that both posit…

LHC Forward Physics

K. Akiba, M. Akbiyik, M. Albrow +184

The goal of this report is to give a comprehensive overview of the rich field of forward physics, with a special attention to the topics that can be studied at the LHC. The report…

Bound muon decay spectrum in the leading logarithmic accuracy

Robert Szafron, Andrzej Czarnecki

We compute the dominant, logarithmically enhanced radiative corrections to the electron spectrum in the bound muon decay in the whole experimentally interesting range. The correcte…

Two-loop Bhabha Scattering at High Energy beyond Leading Power Approximation

Alexander A. Penin, Nikolai Zerf

We evaluate the two-loop contribution to the wide-angle high-energy electron-positron scattering in the double-logarithmic approximation. The origin and the gen…

Lepton Number Violation and `Diracness' of massive neutrinos composed of Majorana states

Janusz Gluza, Tomasz Jelinski, Robert Szafron

Majorana neutrinos naturally lead to a Lepton Number Violation (LNV). A superposition of Majorana states can mimic Dirac-type neutrinos, leading to its conservation (LNC). We demon…

On the light quark mass effects in Higgs boson production in gluon fusion

Kirill Melnikov, Alexander Penin

Production of Higgs bosons at the LHC is affected by the contribution of light quarks, that mediate the gg \to Hg transition. Although their impact is suppressed by small Yukawa co…

Electron contribution to the muon anomalous magnetic moment at four loops

Alexander Kurz, Tao Liu, Peter Marquard +3

We present results for the QED contributions to the anomalous magnetic moment of the muon containing closed electron loops. The main focus is on perturbative corrections at four-lo…

Improved limits on dark matter annihilation in the Sun with the 79-string IceCube detector and implications for supersymmetry

IceCube Collaboration, M. G. Aartsen, K. Abraham +315

We present an improved event-level likelihood formalism for including neutrino telescope data in global fits to new physics. We derive limits on spin-dependent dark matter-proton s…
