Collider versus cosmic ray sensitivity to black hole production
Abstract In scenarios with extra dimensions and TeV-scale quantum gravity, black holes are expected to be produced copiously at center-of-mass energies above the fundamental Planck scale. The Large Hadron Collider (LHC) may thus turn into a factory...

Precise neutron magnetic form factors
Abstract Precise data on the neutron magnetic form factor G mn have been obtained with measurements of the ratio of cross sections of D(e,e′n) and D(e,e′p) up to momentum transfers...

Complex flavour couplings in supersymmetry and unexpected CP violation in the decay B→φK
Abstract Complex flavour couplings (off-diagonal mass terms) in the squark sector of supersymmetric theories may drastically alter both the rate and the CP-violating asymmetry of certain B-meson decays. We consider the effects of couplings that...

Forces between stable non-BPS branes
Abstract As a step toward constructing realistic brane world models in string theory, we consider the interactions of a pair of non-BPS branes. We construct a dyonic generalization of the non-BPS branes first constructed by Bergman, Gaberdiel and...

Lattice chiral symmetry, Yukawa couplings and the Majorana condition
Abstract It is shown that the conflict between lattice chiral symmetry and the Majorana condition in the presence of Yukawa couplings, which was noted in our previous Letter, is related in an essential way to the basic properties of Ginsparg–Wilson...

Oscillation Regimes of Dynamic Parameters Changing in Couette Flow of Anomalous Thermoviscous Liquids
Abstract In this work results of researches of the hydrodynamic systems behavior describing a Taylor-Couette flow are presented. The subject being examined consisted in determining the influence of interdependence between viscosity and temperature...

Performance and lifetime of micro-channel plate tubes for the TORCH detector
Abstract Timing Of internally Reflected CHerenkov photons (TORCH) is a time-of-flight detector proposed for particle identification at low momentum. Charged particles passing through a plane of quartz produce Cherenkov light, some of which is...

Possible emission of cosmic X- and γ-rays by unstable particles at late times
Abstract We find that charged unstable particles as well as neutral unstable particles with non-zero magnetic moment which live sufficiently long may emit electromagnetic radiation. This new mechanism is connected with the properties of unstable...

Inclusive isolated photons in pp and PbPb collisions at 2.76 TeV with CMS
Abstract The CMS detector at the LHC has been used to measure the yield of isolated photons in both proton–proton and lead–lead collisions at a nucleon–nucleon center of mass energy of 2.76 TeV. Photons were detected in the pseudorapidity range ...

High-velocity Impact Fragmentation of Brittle, Granular Aluminum Spheres
Abstract We present ballistic and fragmentation data for brittle, granular aluminum spheres following high- velocity impact (0.5-2.0km/s) on thin steel plates. These spheres, formed from isostatically pressed alu- minum powder, are representative of ...

Single-valued Hamiltonian via Legendre–Fenchel transformation and time translation symmetry
Abstract Under conventional Legendre transformation, systems with a non-convex Lagrangian will result in a multi-valued Hamiltonian as a function of conjugate momentum. This causes problems such as non-unitary time evolution of quantum state and...

Lagrangian for the Frenkel electron
Abstract We found Lagrangian action which describes spinning particle on the base of non-Grassmann vector and involves only one auxiliary variable. It provides the right number of physical degrees of freedom and yields generalization of the Frenkel...

Localisation of defects with time and frequency measurements using pulsed arrays
Abstract The frequency dependent directivity of the periodic permanent magnet transducer is used to extract information about the position of any discontinuities present in a sample. Two approaches are used: narrowband excitation and broadband...
