Soft matters, or the recursions with massive spinors

open access: yesJournal of High Energy Physics, 2021
We discuss recursion relations for scattering amplitudes with massive particles of any spin. They are derived via a two-parameter shift of momenta, combining a BCFW-type spinor shift with the soft limit of a massless particle involved in the process. The

Radiation reaction for spinning black-hole scattering

open access: yesPhysics Letters B, 2022
Starting from the leading soft term of the 5-point amplitude, involving a graviton and two Kerr black holes, that factorises into the product of the elastic amplitude without the graviton and the leading soft factor, we compute the infrared divergent ...

Study of Electrical Properties of p-PbSe/p-Si Heterojunction [PDF]

open access: yesEngineering and Technology Journal, 2007
Electrical properties of p-PbSe/p-Si heterojunction detector have beeninvestigated. The electrical properties under dark condition show a rectifyingbehaviour with low rectification factor, and exhibits soft breakdown reversecurrent.C-V characteristics ...

(bi)*-Neutrosophic Soft Limit Points in Neutrosophic Soft Bitopological Space

open access: yesJOURNAL OF UNIVERSITY OF BABYLON for Pure and Applied Sciences, 2022
The major goal of the current research is to present the conception of “(bi)*-neutrosophic soft limit points” in “neutrosophic soft Bitopological” spaces. In addition, the research aims to give the essential theorems related to the topic with illustrative ...

R^4 counterterm and E7(7) symmetry in maximal supergravity [PDF]

open access: yes, 2009
The coefficient of a potential R^4 counterterm in N=8 supergravity has been shown previously to vanish in an explicit three-loop calculation. The R^4 term respects N=8 supersymmetry; hence this result poses the question of whether another symmetry could ...

Symbology for elliptic multiple polylogarithms and the symbol prime

open access: yesJournal of High Energy Physics, 2023
Elliptic multiple polylogarithms occur in Feynman integrals and in particular in scattering amplitudes. They can be characterized by their symbol, a tensor product in the so-called symbol letters.

Anomalous U(1) as a mediator of Supersymmetry Breaking [PDF]

open access: yes, 1996
We point out that an anomalous gauge U(1) symmetry is a natural candidate for being the mediator and messenger of supersymmetry breaking. It facilitates dynamical supersymmetry breaking even in the flat limit.

The infrared structure of Nambu-Goldstone bosons

open access: yesJournal of High Energy Physics, 2018
The construction of effective actions for Nambu-Goldstone bosons, and the nonlinear sigma model, usually requires a target coset space G/H. Recent progresses uncovered a new formulation using only IR data without reference to the broken group G in the UV,

Quantum critical origin of the superconducting dome in SrTiO$_3$ [PDF]

open access: yes, 2015
We investigate the origin of superconductivity in doped SrTiO$_3$ (STO) using a combination of density functional and strong coupling theories within the framework of quantum criticality. Our density functional calculations of the ferroelectric soft mode
