Next-to-Leading-Order Calculation of the Light Tensor $(J^{P} = 2^{+})$ Hybrid Correlation Function

R. T. Kleiv, J. Ho, S. Li +3

We report on the QCD calculations underlying a next-to-leading-order (NLO) QCD Laplace sum-rule analysis of the light tensor $(J^{P} = 2^{+})$ hybrid meson mass and coupling. This arti…

$2^{++}$ Light Tensor Hybrid Meson from QCD Laplace Sum Rules

Jason Ho, Robin Kleiv, Siyuan Li +3

We present an analysis of the light tensor ( $J^{P C} = 2^{++}$ ) hybrid meson mass and coupling from QCD Laplace Sum Rules where the next-to-leading order (NLO) perturbative (PT) corre…

QCD condensates and $α_{s}$ from $e^{+} e^{-}$ and $τ$ -decays

Stephan Narison

In this talk, I review the determinations of the QCD condensates and $α_{s}$ within the SVZ expansion using the ratio of Laplace sum rule (LSR) and $τ$ -like moments in $e^+e^-\to I=1…

Revisiting the Muon Anomaly from $e^{+} e^{-} \to$ Hadrons

Stephan Narison

In this talk, I revisit and present a more comprehensive estimate of the lowest order Hadronic Vacuum Polarization (HVP) contribution $a_{μ} ∣_{h v p}^{l o}$ to the muon anomalous ma…

$2^{++}$ Di-gluonium from LSR at higher order

Siyuan Li, Stephan Narison, Davidson Rabetiarivony +1

We improve the determination of the mass and coupling of the $2^{++}$ tensor di-gluonium by using relativistic QCD Laplace sum rules (LSR). In so doing, we evaluate the next-to-lea…

QCD parameters and SM-high precision from $e^{+} e^{-}$ to Hadrons: Updated

Stephan Narison

1. I update my previous comparison of the theoretical value of the muon anomaly with the new measurement and found $Δa_μ\equiv a_μ^{exp}-a_μ^{th} = (143\pm 42_{th}\pm 22_{exp})\tim…

$2^{++}$ Tensor Di-Gluonium from Laplace Sum Rules at NLO

S. Li, S. Narison, T. Steele +1

We evaluate the next-to-leading (NLO) corrections to the perturbative (PT) and $< α_{s} G^{2} >$ condensate and the LO constant term of the $< G^{3} >$ contributions to the $2^{++}$ tens…

The New Charm-Strange Resonances in the D^- K^+ Channel

R. M. Albuquerque, S. Narison, D. Rabetiarivony +1

We evaluate the masses and decay constants of the $0^{+}$ and $1^{-}$ open-charm $(c ˉ d ˉ) (u s)$ tetraquarks and molecular states from QCD spectral sum rules (QSSR) by using QCD…

Z_c -like spectra from QCD Laplace sum rules at NLO

R. M. Albuquerque, S. Narison, D. Rabetiarivony

We present a global analysis of the observed Z_c, Z_cs and future Z_css-like spectra using the inverse Laplace transform (LSR) version of QCD spectral sum rules (QSSR) within stabi…

Doubly-hidden scalar heavy molecules and tetraquarks states from QCD at NLO

R. M. Albuquerque, S. Narison, A. Rabemananjara +2

Alerted by the recent LHCb discovery of exotic hadrons in the range (6.2 -- 6.9) GeV, we present new results for the doubly-hidden scalar heavy $(Q ˉ Q) (Q Q ˉ)$ charm and beau…

$D ˉ^{} D$ and $B ˉ^{} B (1^{++})$ molecules at N2LO from QSSR

F. Fanomezana, S. Narison, A. Rabemananjara

We use QCD spectral sum rules (QSSR) and the factorization properties of molecule currents to estimate the masses and couplings of the $D ˉ^{*} D$ and $B ˉ^{*} B (1^{++})$ molecule…

Light Hybrid Mesons in QCD

K. G. Chetyrkin, Stephan Narison

Including the radiative perturbative corrections and the short distance tachyonic gluon mass effects which mimic the ones of UV renormalons, we re-estimate the decay amplitudes, ma…

{ $K^{0}$ }-{ $K^{0}$ } mixing and the CKM parameters $(ρ, η)$ from the Laplace sum rules

S. Narison

Using the Laplace sum rule (LSR) approach, which is less affected by the contribution of the higher mass hadronic states than the Finite Energy Sum Rule (FESR), we test the reliabi…

S. Narison

Using the {\it hybrid} moments-Laplace sum rule (HSR), which is well-defined for $M_b \rar \infty$, in contrast with the $p o p u l a r$ double Borel (Laplace) sum rule (DLSR), which blo…

Upsilon \bar BB$ Couplings, Slope of the Isgur-Wise Function and Improved Estimate of \boldmath{$V_{cb}$}}

S. Narison

We estimate the sum of the $Υ B ˉ B$ couplings using QCD Spectral Sum Rules (QSSR). Our result implies the phenomenological bound $ξ^{'} (v v^{'} = 1) \geq - 1.04$ for the slope of the Isgu…
