Title: An ϵ′ improvement from right-handed currents

Abstract

Recent lattice QCD calculations of direct CP violation in K_L → ππ decays indicate tension with the experimental results. Assuming this tension to be real, we investigate a possible beyond-the-Standard Model explanation via right-handed charged currents. By using chiral perturbation theory in combination with lattice QCD results, we accurately calculate the modification of ϵ'/ϵ induced by right-handed charged currents and extract values of the couplings that are necessary to explain the discrepancy, pointing to a scale around 10–100 TeV. We find that couplings of this size are not in conflict with constraints from other precision experiments, but next-generation hadronic electric dipole moment searches (such as neutron and ²²⁵Ra) can falsify this scenario. As a result, we work out in detail a direct link, based on chiral perturbation theory, between CP violation in the kaon sector and electric dipole moments induced by right-handed currents which can be used in future analyses of left-right symmetric models.

Isospin-violating contributions to ϵ'/ϵ

Journal Article Cirigliano, Vincenzo ; Gisbert, Hector ; Pich, Antonio ; ... - Journal of High Energy Physics (Online)

The known isospin-breaking contributions to the K → ππ amplitudes are reanalyzed, taking into account our current understanding of the quark masses and the relevant non-perturbative inputs. We present a complete numerical reappraisal of the direct CP-violating ratio ϵ'/ϵ, where these corrections play a quite significant role. We obtain the Standard Model prediction Re (ϵ'/ϵ) = (14 ± 5) · 10^-4, which is in very good agreement with the measured ratio. The uncertainty, which has been estimated conservatively, is dominated by our current ignorance about 1/N_C-suppressed contributions to some relevant chiral-perturbation-theory low-energy constants.

P and CP nonconservation through Higgs exchange in gauge models with right-handed charged currents

Journal Article Deshpande, N G ; Ma, E - Phys. Rev., D; (United States)

The recent proposal of Weinberg that CP violation occurs through the exchange of charged Higgs bosons is examined in detail for gauge models with right-handed charged currents. We find that parity must be violated as well through the exchange of neutral Higgs bosons. In a five-quark model, this effect could be considerably bigger than that of the usual weak interaction, and should be looked for in psi' ..-->.. psi..pi pi.. and psi' ..-->.. psi..pi../sup 0/ as a test of this whole theoretical framework. Other interesting phenomena are the enhanced production of certain Higgs bosons and a value for the neutronmore »« less

Baryon mass splittings and strong $CP$ violation in SU(3) chiral perturbation theory

Journal Article de Vries, Jordy ; Mereghetti, Emanuele ; Walker-Loud, Andre P. - Physical Review C, Nuclear Physics

We study SU(3) flavor-breaking corrections to the relation between the octet baryon masses and the nucleon-meson CP-violating interactions induced by the QCD θ¯ term. We work within the framework of SU(3) chiral perturbation theory and work through next-to-next-to-leading order in the SU(3) chiral expansion, which is O(mq2). At lowest order, the CP-odd couplings induced by the QCD θ¯ term are determined by mass splittings of the baryon octet, the classic result of Crewther et al. [Phys. Lett. B 88, 123 (1979)PYLBAJ0370-269310.1016/0370-2693(79)90128-X]. We show that for each isospin-invariant CP-violating nucleon-meson interaction there exists one relation that is respected by loop correctionsmore »« less

Lattice QCD spectroscopy for hadronic CP violation

Journal Article de Vries, Jordy ; Mereghetti, Emanuele ; Seng, Chien-Yeah ; ... - Physics Letters B

© 2017 The interpretation of nuclear electric dipole moment (EDM) experiments is clouded by large theoretical uncertainties associated with nonperturbative m atrix elements. In various beyond-the-Standard Model scenarios nuclear and diamagnetic atomic EDMs are expected to be dominated by CP-violating pion–nucleon interactions that arise from quark chromo-electric dipole moments. The corresponding CP-violating pion–nucleon coupling strengths are, however, poorly known. In this work we propose a strategy to calculate these couplings by using spectroscopic lattice QCD techniques. Instead of directly calculating the pion–nucleon coupling constants, a challenging task, we use chiral symmetry relations that link the pion–nucleon couplings to nucleon sigmamore »« less

Reanalysis of strong CP -violating effects in chiral perturbation theory

Journal Article Cheng, H - Physical Review, D (Particles Fields); (USA)

Strong {ital CP}-violating effects induced by the QCD {theta} term, e.g., the {eta}{r arrow}{pi}{pi} decay, the {ital CP}-odd pion-nucleon coupling, and the electric dipole moment of the neutron are reanalyzed in chiral perturbation theory in which strong {ital CP} violation manifests itself in the meson and baryon sectors. Corrections to previous current-algebra results are calculated. We show that strong {ital CP} phenomena do respect the general constraint that, as stressed recently by Aoki and Hatsuda, they vanish in the absence of the gluonic anomaly and/or in the chiral limit. The neutron electric dipole moment induced at the tree level ismore »« less
