Differential equations and dispersion relations for Feynman amplitudes. The two-loop massive sunrise and the kite integral
Abstract It is shown that the study of the imaginary part and of the corresponding dispersion relations of Feynman graph amplitudes within the differential equations method can provide a powerful tool for the solution of the equations, especially in ...

Determination of CP violation parameter using neutrino pair beam
Abstract Neutrino oscillation experiments under neutrino pair beam from circulating excited heavy ions are studied. It is found that detection of double weak events has a good sensitivity to measure CP violating parameter and distinguish mass...

Quasi Stable Solitons Generated by Landscape
Abstract Based on the landscape idea we consider solitons formation during inflation. We consider special case of scalar field dynamics and discuss characteristics of non-trivial field configurations, obtained in our approach. ...

Highlight on Supernova Early Warning at Daya Bay
Abstract Providing an early warning of supernova burst neutrinos is of importance in studying both supernova dynamics and neutrino physics. The Daya Bay Reactor Neutrino Experiment, with a unique feature of multiple liquid scintillator detectors, is ...

Azimuthal anisotropies in p+Pb collisions from classical Yang–Mills dynamics
Abstract We compute single and double inclusive gluon distributions in classical Yang–Mills simulations of proton–lead collisions and extract the associated transverse momentum dependent Fourier harmonics ...

A SUSY inspired simplified model for the 750 GeV diphoton excess
Abstract The evidence for a new neutral scalar particle from the 750 GeV diphoton excess, and the absence of any other signal of new physics at the LHC so far, suggests the existence of new coloured scalars. To study this possibility, we propose a...

Single Shot Radiography Using an All-optical Compton Backscattering Source
Abstract The development of compact laser-based synchrotron sources is a field of active research. Here we present recent results on an all-optical Compton backscattering source using laser-accelerated electrons and a plasma mirror, as introduced in ...

Monitoring of Ion Purity in High-energy Implant via RBS
Abstract The UAlbany Dynamitron is used for high-energy ion implantation as well as for routine materials analysis. Its ion source can be run using any one of fourteen different gases, leading to concerns of contamination during an implantation. The ...

Measurement of the Z boson differential cross section in transverse momentum and rapidity in proton–proton collisions at 8 TeV
Abstract We present a measurement of the Z boson differential cross section in rapidity and transverse momentum using a data sample of pp collision events at a centre-of-mass energy s ...

Supersymmetry breaking as a new source for the generalized uncertainty principle
Abstract In this letter, we will demonstrate that the breaking of supersymmetry by a non-anticommutative deformation can be used to generate the generalized uncertainty principle. We will analyze the physical reasons for this observation, in the...

First-principles Theory of the Momentum-dependent Local Ansatz for Correlated Electron System
Abstract The momentum-dependent local-ansatz (MLA) wavefunction describes well correlated electrons in solids in both the weak and strong interaction regimes. In order to apply the theory to the realistic system, we have extended the MLA to the...

The software library of the Belle II experiment
Abstract A next generation B factory and the detector counterpart, SuperKEKB and Belle II, are being built in Japan, as the upgrades of KEKB and Belle, respectively. The new collider will start its commissioning in 2015. This is an ambitious...

T-duality of α′-correction to DBI action at all orders of gauge field
Abstract By explicit calculations of four-field couplings, we observe that the higher derivative corrections to the DBI action in flat space–time, can be either in a covariant form or in a T-duality invariant form. The two forms are related by a...

Contribution of Amplitude Holographic Grating to Diffraction Efficiency of Mixed Transmission Holograms in Photorefractive Bi12TiO20 Piezocrystal
Abstract The results of experimental and theoretical studies of the readout process of the mixed transmission holograms recorded in a photorefractive Bi12TiO20 piezocrystal are presented. It is shown, that in comparison with the case of pure phase...

Compact Q-balls
Abstract In this work we deal with non-topological solutions of the Q-ball type in two space–time dimensions, in models described by a single complex scalar field that engenders global symmetry. The main novelty is the presence of stable Q-balls...
