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.

Critical properties of hadronic matter in thermodynamical models

Physics Letters B, 1976
Abstract The temperature T 0 in certain thermodynamical models for strongly interacting systems taken as the critical point yields directly the critical exponents for the specific heat and compressibility. We discuss the implications of thermodynamical scaling using various asymptotic conditions.

Chiral properties of hadron correlators in nuclear matter

Nuclear Physics A, 2000
The constraints imposed by chiral symmetry on hadron correlation functions in nuclear medium are discussed. It is shown that these constraints imply a certain structure for the in-medium hadron correlators and lead to the cancelation of the order $ m_ $ term in the in-medium nucleon correlator.

Probing leptophobic dark sector with a pseudoscalar portal in the NA64 experiment at CERN

Journal of High Energy Physics
We propose the possibility of discovering a light pseudoscalar particle a, axion-like particle (ALP), interacting mainly with quarks using the electron and photon scattering reaction chain e + Z → e + γ + Z; γ + Z → a + Z on nuclei in the NA64 experiment

Final Results on Heavy Quarks at LEP and SLD

, 2002
In the last decade, the LEP and SLD experiments played a central role in the study of B hadrons (hadrons containing a b quark). New B hadrons have been observed ($B^0_s$, \Lambda_b$, $\Xi_b$ and $B^{**}$) and their production and decay properties have ...

Tetraquarks at large M and large N

Journal of High Energy Physics
We study tetraquarks in large N QCD with heavy quarks, in the domain where non-relativistic quantum mechanics offers an adequate approximation. Within the regime of validity of the Born-Oppenheimer approximation, we systematically study and explicitly ...

The determination of the spin and parity of a vector-vector system

Journal of High Energy Physics
We present a construction of the reaction amplitude for the inclusive production of a resonance decaying to a pair of identical vector particles such as J/ψJ/ψ, ρρ, ϕϕ. The method provides the possibility of determining the spin and parity of a resonance

Hypercentral Constituent Quark Model and Isospin for the Baryon Static Properties [PDF]

Journal of Sciences, Islamic Republic of Iran, 2005
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron.
