Properties and decays of b-hadrons at D0.

, 2012
The Tevatron, with $p\bar{p}$ collisions at $\sqrt{s}=$ \unit{1.96}{\TeV}, can produce all flavours of $b$ hadrons and allows several studies in the $B$ physics sector. This paper presents a selection of recent results on heavy hadron physics using data up to 10.4 fb$^{-1}$ of integrated luminosity collected with the D\O\ detector.

Revising the mass of light hybrid mesons: NLO QCD sum rules point to ϕ(2170) as a prime candidate

Journal of High Energy Physics
We present a comprehensive next-to-leading order (NLO) QCD sum rule analysis for light hybrid mesons with J PC = 1 −− , incorporating condensates up to dimension-8 and NLO corrections to the perturbative, gluon condensate, and four-quark condensate ...

Hyperon semileptonic decays in QCD sum rules

Journal of High Energy Physics
We investigate the hyperon semileptonic decays within the framework of QCD sum rules. The flavor SU(3) symmetry breaking effects are analyzed via the relevant form factors and corresponding branching fractions.

Gravitational form factors of the baryon octet in holographic QCD

Journal of High Energy Physics
The gravitational form factors (GFFs) of the baryon octet, including hyperons, are investigated in a bottom-up holographic QCD model that explicitly incorporates the SU(3) flavor symmetry breaking through the strange quark mass.

On the Energy Budget of Quarks and Hadrons, Their Inconspicuous “Strong Charge”, and the Impact of Coulomb Repulsion on the Charged Ground States

Particles
We review and meta-analyze particle data and properties of hadrons with measured rest masses. The results of our study are summarized as follows. (1) The strong-force suppression of the repulsive Coulomb forces between quarks is sufficient to explain the

CP Violation: Differing Binding Energy Levels of Quarks and Antiquarks, and Their Transitions in Λ-Baryons and B-Mesons

Foundations
We consider spontaneous quark transitions between the Λ0 baryon and its resonant states, and (anti)quark transitions between the neutral kaon K0 and the two heavy ηq-mesons (q = c, b).

Exploring Efimov states in D * D * D * and DD * D * three-body systems

Journal of High Energy Physics
The Efimov effect is an intriguing three-body quantum phenomenon. Searching for Efimov states within the realms of nuclear and hadronic physics presents a challenge due to the inherent inability of natural physical systems to exhibit adjustable two-body ...

The ρ(770, 1450) → ωπ contributions for three-body decays B → D ¯ ∗ ωπ $$ B\to {\overline{D}}^{\left(\ast \right)}\omega \pi $$

Journal of High Energy Physics
The decays B → D ¯ ∗ ωπ $$ B\to {\overline{D}}^{\left(\ast \right)}\omega \pi $$ are very important for the investigation of ρ excitations and the test of factorization hypothesis for B meson decays. The B + → D ¯ ∗ 0 ω π + $$ {B}^{+}\to {\overline{D}}^{\

Z c and Z cs systems with operator mixing at NLO in QCD sum rules

Journal of High Energy Physics
We study the mass spectra of hidden-charm tetraquark systems with quantum numbers (I G )J P = (1+)1+ (and their I = 1 2 $$ \frac{1}{2} $$ partners) using QCD sum rules.
