Experimental indication on chiral symmetry restoration in meson spectrum
Abstract The spectroscopic predictions of the Ademollo–Veneziano–Weinberg dual model are critically tested in view of the modern experimental data. The predicted equidistance of masses squared for chiral partners is shown to be violated high in...

The forward–backward asymmetry at NNLO revisited
Abstract I reconsider the forward–backward asymmetry for flavoured quarks in electron–positron annihilation. I suggest an infrared-safe definition of this observable, such that the asymmetry may be computed in perturbative QCD with massless quarks....

Corrections to the fine structure constant in the spacetime of a cosmic string from the generalized uncertainty principle
Abstract We calculate the corrections to the fine structure constant in the spacetime of a cosmic string. These corrections stem from the generalized uncertainty principle. In the absence of a cosmic string our result here is in agreement with our...

Signals of CPT violation and non-locality in future neutrino oscillation experiments
Abstract We investigate the sensitivities of future neutrino oscillation experiments for measuring the neutrino mass squared differences and leptonic mixing angles independently with neutrinos and anti-neutrinos. We update the expected sensitivities ...

Observable (?) cosmological signatures of superstrings in pre-big bang models of inflation
Abstract The different couplings of the dilaton to the U ( 1 ) gauge field of heterotic and type I superstrings may leave an...

Is our universe decaying at an astronomical rate?
Abstract Unless our universe is decaying at an astronomical rate (i.e., on the present cosmological timescale of Gigayears, rather than on the quantum recurrence timescale of googolplexes), it would apparently produce an infinite number of observers ...

Trans-Planckian footprints in inflationary cosmology
Abstract We consider a minimum uncertainty vacuum choice at a fixed energy scale Λ as an effective description of trans-Planckian physics, and discuss its implications for the linear perturbations of a massless scalar field in power-law inflationary ...

Simulating and Compiling Code for the Sequential Quantum Random Access Machine
Abstract We present the SQRAM architecture for quantum computing, which is based on Knill's QRAM model. We detail a suitable instruction set, which implements a universal set of quantum gates, and demonstrate the operation of the SQRAM with...

THz imaging and spectroscopy using intense THz sources at the advanced laser light source
Abstract There has recently been a surge of new laser-based techniques for generating intense, few-cycle terahertz (THz) pulses, thus opening new applications, such as studying the nonlinear optical properties of various materials at THz...

Depth-dependent Spin Dynamics in TbMnO3 Thin Films Measured by Low Energy Muon Spin Relaxation
Abstract We report on low energy muon measurements performed on 100nm and 28nm thin epitaxial, highly strained and twin free TbMnO3 films grown on (110) YAlO3 substrates by pulsed laser deposition (λ = 248nm, ν = 2Hz, TS = 760°C). These...

Cosmological two-stream instability
Abstract Two-stream instability requires, essentially, two things to operate: a relative flow between two fluids and some type of interaction between them. In this Letter we provide the first demonstration that this mechanism may be active in a...

Studies of correlations between D and D mesons in high energy photoproduction
Abstract Studies of DD correlations for a large sample of events containing fully and partially reconstructed pairs of charmed D mesons recorded by the Fermilab photoproduction experiment FOCUS (FNAL-E831) are presented....

Guidance law with impact time and impact angle constraints
Abstract A novel closed-form guidance law with impact time and impact angle constraints is proposed for salvo attack of anti-ship missiles, which employs missile’s normal acceleration (not jerk) as the control command directly. Firstly, the impact...
