Sampling from known probability distributions is a ubiquitous task in computational science,
underlying calculations in domains from linguistics to biology and physics. Generative …

Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

A highly significant structure is observed in the Λ c+ K-π+ π+ mass spectrum, where the Λ c+
baryon is reconstructed in the decay mode p K-π+. The structure is consistent with …

The last decade has seen a marked shift in how the internal structure of hadrons is
understood. Modern experimental facilities, new theoretical techniques for the continuum …

Since the discovery of the first charmed meson in 1976, many open-charm and open-bottom
hadrons were observed. In 2003 two narrow charm-strange states $ D_ {s0}^{\ast}(2317) …

Visible matter is characterised by a single mass scale; namely, the proton mass. The
proton's existence and structure are supposed to be described by quantum chromodynamics …

Measurements of the Λ b→ p ℓ-ν¯ ℓ and Λ b→ Λ c ℓ-ν¯ ℓ decay rates can be used to
determine the magnitudes of the Cabibbo-Kobayashi-Maskawa matrix elements V ub and V …

For very heavy quarks Q, relations derived from heavy-quark symmetry predict the existence
of novel narrow doubly heavy tetraquark states of the form Q i Q jq¯ kq¯ l (subscripts label …

Using a relativized diquark model Hamiltonian, we calculate the masses of J^ PC= 0^++ J
PC= 0++ ground-state tetraquarks in the following systems: bs ̄ b ̄ s bsb¯ s¯, bb ̄ n ̄ n …

We calculate the masses of the(;) tetraquark states with the aid of heavy diquark-antiquark
symmetry (HDAS) and the chromomagnetic interaction (CMI) model. The masses of the …
