Novel applications of Lattice QCD: Parton Distributions, proton charge radius and neutron electric dipole moment

open access: yesEPJ Web of Conferences, 2017
We briefly discuss the current status of lattice QCD simulations and review selective results on nucleon observables focusing on recent developments in the lattice QCD evaluation of the nucleon form factors and radii, parton distribution functions and ...

750 GeV diphoton resonance and electric dipole moments

open access: yesPhysics Letters B, 2016
We examine the implication of the recently observed 750 GeV diphoton excess for the electric dipole moments of the neutron and electron. If the excess is due to a spin zero resonance which couples to photons and gluons through the loops of massive vector-

Improved indirect limits on charm and bottom quark EDMs

open access: yesJournal of High Energy Physics, 2022
We derive indirect limits on the charm and bottom quark electric dipole moments (EDMs) from paramagnetic AMO and neutron EDM experiments. The charm and bottom quark EDMs generate CP-odd photon-gluon operators and light quark EDMs at the c- and b-quark ...

The neutron electric dipole form factor in the perturbative chiral quark model

open access: yes, 2006
We calculate the electric dipole form factor of the neutron in a perturbative chiral quark model, parameterizing CP-violation of generic origin by means of effective electric dipole moments of the constituent quarks and their CP-violating couplings to ...

Schiff moment of the Mercury nucleus and the proton dipole moment

open access: yes, 2003
We calculated the contribution of internal nucleon electric dipole moments to the Schiff moment of $^{199}$Hg. The contribution of the proton electric dipole moment was obtained via core polarization effects that were treated in the framework of random ...

Bound states of a fermion-dyon system

open access: yesEuropean Physical Journal C: Particles and Fields
The bound states of fermions in the external field of an Abelian dyon are studied here both analytically and numerically. Their existence is due to the dyon’s electric charge resulting from a polarization of the fermionic vacuum. The configuration of the

Neutron electric dipole moment in lattice QCD [PDF]

open access: yesPhysical Review Letters, 1989
We present an exploratory computation of the electric dipole moment of the neutron induced by a {ital CP}-violating {theta} term in the QCD Lagrangian in the framework of quenched lattice QCD. We find {ital d}{sub {ital N}}{approx}{minus}4{times}10{sup {minus}14}{theta}e cm.

Microscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2010
The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined.

Electric dipole moments in the minimal scotogenic model

open access: yesJournal of High Energy Physics, 2018
In this work we consider a minimal version of the scotogenic model capable of accounting for an electron electric dipole moment within experimental sensitivity reach in addition to providing a dark matter candidate and radiatively generating neutrino ...

Effective field theory interpretation of lepton magnetic and electric dipole moments

open access: yesJournal of High Energy Physics, 2021
We perform a model-independent analysis of the magnetic and electric dipole moments of the muon and electron. We give expressions for the dipole moments in terms of operator coefficients of the low-energy effective field theory (LEFT) and the Standard ...
