New dispersion relations in the description of $\pi\pi$ scattering amplitudes [PDF]

, 2008
We present a set of once subtracted dispersion relations which implement crossing symmetry conditions for the $\pi\pi$ scattering amplitudes below 1 GeV.

Wave Dispersion Behavior in Quasi-Solid State Concrete Hydration

Sensors, 2023
This paper aims to investigate wave dispersion behavior in the quasi-solid state of concrete to better understand microstructure hydration interactions. The quasi-solid state refers to the consistency of the mixture between the initial liquid–solid stage

Minimal Position-Velocity Uncertainty Wave Packets in Relativistic and Non-relativistic Quantum Mechanics

, 2009
We consider wave packets of free particles with a general energy-momentum dispersion relation $E(p)$. The spreading of the wave packet is determined by the velocity $v = \p_p E$. The position-velocity uncertainty relation $\Delta x \Delta v \geq {1/2} ||$

P-Wave Dispersion in Acute Pancreatitis

Archives of Basic and Clinical Research
Objective: Cardiac complications and electrocardiographic anomalies are frequently seen in acute pancreatitis (AP). Also, an increased P-wave dispersion (PWD) is accepted as a predictor of atrial fibrillation.

Thresholds for global existence and blow-up in a general class of doubly dispersive nonlocal wave equations [PDF]

, 2013
In this article we study global existence and blow-up of solutions for a general class of nonlocal nonlinear wave equations with power-type nonlinearities, $u_{tt}-Lu_{xx}=B(- |u|^{p-1}u)_{xx}, ~(p>1)$, where the nonlocality enters through two pseudo ...

Application of dispersion relations to low-energy meson-nucleon scattering [PDF]

, 1957
Relativistic dispersion relations are used to derive equations for low-energy S-, P-, and D-wave meson-nucleon scattering under the assumption that the (3,3) resonance dominates the dispersion integrals.

Multipole analysis of pion photoproduction based on fixed t dispersion relations and unitarity [PDF]

, 1997
We have analysed pion photoproduction imposing constraints from fixed t dispersion relations and unitarity. Coupled integral equations for the S and P wave multipoles were derived from the dispersion relations and solved by the method of Omnes and ...

Proposal to observe the strong Van der Waals force in e+\bar{e} -> 2 \pi

, 2003
Large discrepancy of the p-wave phase shift data $\delta_{1}(\nu)$ of the $\pi$-$\pi$ scattering from those of the dispersion calculation is pointed out.

, 2011
We analyze the performance of quantum ratchets by considering the dynamics of an initially localized wave packet loaded into a flashing periodic potential.
