A cosmological concordance model with dynamical vacuum term
Abstract We demonstrate that creation of dark-matter particles at a constant rate implies the existence of a cosmological term that decays linearly with the Hubble rate. We discuss the cosmological model that arises in this context and test it...

Spin of a batted baseball
Abstract Experiments are conducted to investigate the spin of a baseball undergoing an oblique collision with a bat. A baseball was fired horizontally at speeds up to 120 mph onto a 3”-diameter cylinder of wood that was rigidly attached to a wall....

Using Fluid Variational Variables to Obtain New Analytic Solutions of Self-Gravitating Flows with Nonzero Helicity
Abstract Flow equations being nonlinear are notoriously difficult to solve analytically. In this work we show that, through a three- independent-functions variational formalism for steady barotropic flows, new analytical solutions of the flow...

Effect of heat radiation in a Walter’s liquid B fluid over a stretching sheet with non-uniform heat source/sink and elastic deformation
Abstract In this present article heat transfer in a Walter’s liquid B fluid over an impermeable stretching sheet with non-uniform heat source/sink, elastic deformation and radiation are reported. The basic boundary layer equations for momentum and...

The ATLAS hadronic tau trigger
Abstract Hadronic decay modes of the tau lepton play an important role in many searches for physics beyond the Standard Model (SM) as well as in SM measurements at the Large Hadron Collider (LHC). However, hadronic tau decays are difficult to...

Design and analysis of moving magnet synchronous surface motor with linear halbach array
Abstract To solve the difficulty of lower speed and precision of conventional stage, a moving magnet type synchronous surface motor (MMSSM) with slotless iron yoke and Halbach array is designed, where the stator and mover are composed of four...

Scalar field quantum cosmology: A Schrödinger picture
Abstract We study the classical and quantum models of a scalar field Friedmann–Robertson–Walker (FRW) cosmology with an eye to the issue of time problem in quantum cosmology. We introduce a canonical transformation on the scalar field sector of the...

Reprint of: Contributions to Jet Noise from Instability Waves and their Interactions: From Theory to Modelling
Abstract Experiment and direct numerical simulation provide compelling evidence that nonlinear wave interactions play a significant role in the generation of noise in subsonic jets. A simple ‘difference mode’ approach captures the essential...

Perturbative quantum gravity on complex spacetime
Abstract In this Letter we will study non-anticommutative perturbative quantum gravity on spacetime with a complex metric. After analysing the BRST symmetry of this non-anticommutative perturbative quantum gravity, we will also analyse the effect of ...

Factorization of heavy-to-light baryonic transitions in SCET
Abstract In the framework of the soft-collinear effective theory, we demonstrate that the leading-power heavy-to-light baryonic form factors at large recoil obey the heavy quark and large energy symmetries. Symmetry breaking effects are suppressed...

Elliptic and triangular flow and their correlation in ultrarelativistic high multiplicity proton–proton collisions at 14 TeV
Abstract The spatial configuration of initial partons in high multiplicity proton–proton scatterings at 14 TeV is assumed as three randomly positioned “hot spots”. The parton momentum distribution in the hot spots is calculated by HIJING2.0 with...

Quantum origin of pre-big-bang collapse from induced matter theory of gravity
Abstract We revisit a collapsing pre-big-bang model of the universe to study with detail the non-perturbative quantum dynamics of the dispersal scalar field whose dynamics becomes from the dynamical foliation of test massless scalar field φ on a 5D...
