On The Origin of Neutrino Mass and Mixing in the Standard Model / McElrath, Bob (CERN)
One can describe cosmological relic neutrinos by adding Lagrange multipliers to the Standard Model Lagrangian for them. [...]

Gaugephobic Higgs Signals at the LHC / Galloway, Jamison (UC, Davis) ; McElrath, Bob (CERN) ; McRaven, John (UC, Davis) ; Terning, John (UC, Davis)
The Gaugephobic Higgs model provides an interpolation between three different models of electroweak symmetry breaking: Higgsless models, Randall-Sundrum models, and the Standard Model. At parameter points between the extremes, Standard Model Higgs signals are present at reduced rates, and Higgsless Kaluza-Klein excitations are present with shifted masses and couplings, as well as signals from exotic quarks necessary to protect the Zbb coupling. [...]

Accurate Mass Determinations in Decay Chains with Missing Energy: II / Cheng, Hsin-Chia (UC, Davis) ; Gunion, John F. (UC, Davis) ; Han, Zhenyu (UC, Davis) ; McElrath, Bob (CERN)
We discuss kinematic methods for determining the masses of the particles in events at a hadron collider in which a pair of identical particles is produced with each decaying via a series of on-shell intermediate beyond-the-SM (BSM) particles to visible SM particles and an invisible particle (schematically, pp -> ZZ + jets with Z -> Aa -> Bba -> Ccba -> ... -> cba...

Measuring neutrino mass with radioactive ions in a storage ring / Lindroos, Mats (CERN) ; McElrath, Bob (CERN) ; Orme, Christopher (CERN ; Durham U., IPPP) ; Schwetz, Thomas (Heidelberg, Max Planck Inst.)
We propose a method to measure the neutrino mass kinematically using beams of ions which undergo beta decay. The idea is to tune the ion beam momentum so that in most decays, the electron is forward moving with respect to the beam, and only in decays near the endpoint is the electron moving backwards. [...]

Laboratory tests for the cosmic neutrino background using beta-decaying nuclei / McElrath, Bob (CERN)
We point out that the Pauli blocking of neutrinos by cosmological relic neutrinos can be a significant effect. For zero-energy neutrinos, the standard parameters for the neutrino background temperature and density give a suppression of approximately 1/2. [...]

Emergent Electroweak Gravity / McElrath, Bob (CERN)
We show that any massive cosmological relic particle with small self-interactions is a super-fluid today, due to the broadening of its wave packet, and lack of any elastic scattering. [...]

There is no explosion risk associated with superfluid Helium in the LHC cooling system / Fairbairn, Malcolm (CERN) ; McElrath, Bob (CERN)
We evaluate speculation about the possibility of a dangerous release of energy within the liquid Helium of the Large Hadron Collider (LHC) cryogenic system due to the occurrence of a "Bose-Nova". [...]

Signatures of Extra Dimensions from Upsilon Decays with a Light Gaugephobic Higgs Boson / Galloway, Jamison (UC, Davis) ; McElrath, Bob (CERN) ; McRaven, John (UC, Davis)
We explore non-standard Higgs phenomenology in the Gaugephobic Higgs model in which the Higgs can be lighter than the usually quoted current experimental bound. The Higgs propagates in the bulk of a 5D space-time and Electroweak Symmetry Breaking occurs by a combination of boundary conditions in the extra dimension and an elementary Higgs. [...]
