Journal ArticleDOI
Towards a unified explanation of R D (*) , R K and (g -2 ) μ anomalies in a left-right model with leptoquarks
TL;DR: In this article, a unified explanation for the decay anomalies in leptonic decay was presented for a minimal left-right symmetric gauge theory motivated by one of the low-energy subgroups of naturally accommodating leptoquarks.
Journal ArticleDOI
Scrutinizing R -parity violating interactions in light of R K ( * ) data
TL;DR: In this paper, the LHCb has measured the ratios of branching fractions in two dilepton invariant mass squared bins, which deviate from the standard model predictions by approximately $25
Journal ArticleDOI
Electromagnetic Charge Radius of the Pion at High Precision
TL;DR: A determination of the pions charge radius from high precision data on the pion vector form factor from both timelike and spacelike regions is presented, using a novel formalism based on analyticity and unitarity.
Journal ArticleDOI
Precise determination of the low-energy hadronic contribution to the muon g-2 from analyticity and unitarity: An improved analysis
TL;DR: In this paper, the authors derived stringent constraints on the two-pion contribution by exploiting analyticity and unitarity of the pion electromagnetic form factor, which is known with high precision in the elastic region from Roy equations for pionpion scattering via the Fermi-Watson theorem.
Journal ArticleDOI
Revisiting B → K * ( → K π ) ν ν ¯ decays
TL;DR: In this paper, the authors investigate resonant and non-resonant backgrounds that arise beyond the narrow-width approximation for the rare decay of the standard model and show that interference-induced effects in the signal region are sizable, as large as 20% in the branching ratio.
