Hadronic light-by-light scattering contribution to the muon anomalous magnetic moment revisited

Kirill Melnikov, Arkady Vainshtein

We discuss hadronic light-by-light scattering contribution to the muon anomalous magnetic moment a_μ^{\rm lbl}, paying particular attention to the consistent matching between the s…

High-precision QCD at hadron colliders: electroweak gauge boson rapidity distributions at NNLO

Charalampos Anastasiou, Lance Dixon, Kirill Melnikov +1

We compute the rapidity distributions of W and Z bosons produced at the Tevatron and the LHC through next-to-next-to leading order in QCD. Our results demonstrate remarkable stabil…

Linear Collider Capabilities for Supersymmetry in Dark Matter Allowed Regions of the mSUGRA Model

Howard Baer, Alexander Belyaev, Tadas Krupovnickas +1

Recent comparisons of minimal supergravity (mSUGRA) model predictions with WMAP measurements of the neutralino relic density point to preferred regions of model parameter space. We…

A new method for real radiation at NNLO

C. Anastasiou, Kirill Melnikov, Frank Petriello

We propose a new method of computing real emission contributions to hard QCD processes. Our approach uses sector decomposition of the exclusive final-state phase space to enable ex…

On the hidden charm state at 3872 MeV

Sandip Pakvasa, Mahiko Suzuki

We discuss some puzzling aspects of the narrow hidden charm resonance that was recently discovered by the Belle Collaboration at mass 3872 MeV. In order to determine its quantum nu…

Sensitivity to and in the Decaying Astrophysical Neutrino Scenario

John F. Beacom, Nicole F. Bell, Dan Hooper +2

We have previously shown that the decay of high-energy neutrinos from distant astrophysical sources would be revealed by flavor ratios that deviate strongly from the $ϕ_{ν_e}:ϕ_{ν_…

Pseudo-Dirac Neutrinos, a Challenge for Neutrino Telescopes

John F. Beacom, Nicole F. Bell, Dan Hooper +3

Neutrinos may be pseudo-Dirac states, such that each generation is actually composed of two maximally-mixed Majorana neutrinos separated by a tiny mass difference. The usual active…

Measuring Flavor Ratios of High-Energy Astrophysical Neutrinos

John F. Beacom, Nicole F. Bell, Dan Hooper +2

We discuss the prospects for next generation neutrino telescopes, such as IceCube, to measure the flavor ratios of high-energy astrophysical neutrinos. The expected flavor ratios a…

Destruction of Nuclear Bombs Using Ultra-High Energy Neutrino Beam

Hirotaka Sugawara, Hiroyuki Hagura, Toshiya Sanami

We discuss the possibility of utilizing the ultra-high energy neutrino beam (about 1000 TeV) to detect and destroy the nuclear bombs wherever they are and whoever possess them.

Dilepton rapidity distribution in the Drell-Yan process at NNLO in QCD

Charalampos Anastasiou, Lance Dixon, Kirill Melnikov +1

We compute the rapidity distribution of the virtual photon produced in the Drell-Yan process through next-to-next-to-leading order in perturbative QCD. We introduce a powerful new…

Reach of the Fermilab Tevatron for minimal supergravity in the region of large scalar masses

Howard Baer, Tadas Krupovnickas, Xerxes Tata

The reach of the Fermilab Tevatron for supersymmetric matter has been calculated in the framework of the minimal supergravity model in the clean trilepton channel. Previous analyse…

Updated Reach of the CERN LHC and Constraints from Relic Density, b->s gamma and a(mu) in the mSUGRA Model

Howard Baer, Csaba Balazs, Alexander Belyaev +2

{We present an updated assessment of the reach of the CERN LHC pp collider for supersymmetric matter in the context of the minimal supergravity (mSUGRA) model. In addition to previ…
