Electroweak corrections to γZ production at hadron colliders
Abstract In this Letter we present the results from a calculation of the full electroweak one-loop corrections for γZ vector-boson pair production at hadron colliders. The cases of proton–antiproton as well as proton–proton collisions, at the...

Neutrino sector impacts SUSY dark matter
Abstract Motivated by the fact that neutrinos are massive, we study the effect of neutrino Yukawa couplings on neutralino dark matter observables within the framework of a supersymmetric seesaw. We find that neutrino couplings significantly affect...

Euclidean solutions of Yang–Mills theory coupled to a massive dilaton
Abstract The Euclidean version of the Yang–Mills theory coupled to a massive dilaton is investigated. Our analytical and numerical results implies the existence of an infinite number of branches of globally regular, spherically symmetric, dyonic...

Determining the spin of supersymmetric particles at the LHC using lepton charge asymmetry
Abstract If signals suggesting supersymmetry (SUSY) are discovered at the LHC then it will be vital to measure the spins of the new particles to demonstrate that they are indeed the predicted super-partners. A method is discussed by which the spins...

Stability of the curvature perturbation in dark sectors' mutual interacting models
Abstract We consider perturbations in a cosmological model with a small coupling between dark energy and dark matter. We prove that the stability of the curvature perturbation depends on the type of coupling between dark sectors. When the dark...

Reprint of: Flow Filtering and the Physical Sources of Aerodynamic Sound
Abstract The physical sources of sound are expressed in terms of the non-radiating part of the flow. The non-radiating part of the flow can be obtained from convolution filtering, as we demonstrate numerically by using an axi-symmetric jet...

Black holes in an ultraviolet complete quantum gravity
Abstract In this Letter we derive the gravity field equations by varying the action for an ultraviolet complete quantum gravity. Then we consider the case of a static source term and we determine an exact black hole solution. As a result we find a...

Entropy of extremal black holes from entropy of quasiblack holes
Abstract The entropy of extremal black holes (BHs) is obtained using a continuity argument from extremal quasiblack holes (QBHs). It is shown that there exists a smooth limiting transition in which (i) the system boundary approaches the extremal...

Zero modes for the boundary giant magnons
Abstract We study the fermion zero-mode dynamics for open strings ending on the giant graviton branes. For the open string ending on the Z = 0 brane, the...

Minimal seesaw model with tri/bi-maximal mixing and leptogenesis
Abstract We examine minimal seesaw mechanism in which the masses of light neutrinos are described with tri/bi-maximal mixing in the basis where the charged-lepton Yukawa matrix and heavy Majorana neutrino mass matrix are diagonal. We search for all...

Modeling of ballistic and trapping effects on the collection efficiency of holes and electrons separately for a planar mercuric iodide detector (HgI2)
Abstract For the room temperature nuclear detector application, signal created in the detector depends not only to the energy of the incident photon but also to the position of the interaction. This can bring an incomplete charge collection caused...

Search for the Standard Model Higgs boson at LEP
Abstract The four LEP Collaborations, ALEPH, DELPHI, L3 and OPAL, have collected a total of 2461 pb−1 of e+e− collision data at centre-of-mass energies between 189 and 209 GeV. The data are used to search for the Standard Model Higgs boson. The...

Analyses of elastically scattered charged pions from 40Ca in the intermediate-energy region
Abstract The data of differential cross sections for elastically scattered charged pions from 40 Ca have been analyzed using a simple local optical potential for 50, 65, and 80MeV incident energies. The nature of these...

Spectral Characterization of a Velocity Selector Type Monochromator for Energy-Selective Neutron Imaging
Abstract The mechanical velocity selector is a device that can be used as wavelength monochromator for energy-selective neutron imaging applications. Its use is desirable in case of moderate wavelength resolution and short exposure times. The...
