A New Look at the $Y$ Tetraquarks and $Ω_{c}$ Baryons in the Diquark Model

Ahmed Ali, Luciano Maiani, Anatoly V. Borisov +5

We analyze the hidden charm $P$ -wave tetraquarks in the diquark model, using an effective Hamiltonian incorporating the dominant spin-spin, spin-orbit and tensor interactions. We c…

Mass spectrum of spin-1/2 pentaquarks with a $c c ˉ$ component and their anticipated discovery modes in $b$ -baryon decays

Ahmed Ali, Ishtiaq Ahmed, M. Jamil Aslam +1

The LHCb discovery of the two baryonic states $P_{c}^{+} (4380)$ and $P_{c}^{+} (4450)$ , having $J^{P} = 3/ 2^{-}$ and $J^{P} = 5/ 2^{+}$ , respectively, in the process $pp \to b b ˉ \to Λ_{b} X$ , fo…

LHCb anomaly in $B \to K^{*} μ^{+} μ^{-}$ optimised observables and potential of $Z^{'}$ Model

Ishtiaq Ahmed, Abdur Rehman

Over the last few years LHCb with present energies found some discrepancies in $b \to s ℓ^{+} ℓ^{-}$ FCNC transitions including anomalies in the angular observables of $B\to K^*μ^+μ…

NNLO QCD counterterm contributions to $B$ \to $X_{s} γ$ for the physical value of $m_{c}$

Mikolaj Misiak, Abdur Rehman, Matthias Steinhauser

One of the most important O( $α_{s}^{2}$ ) corrections to the $B \to X_{s} γ$ branching ratio originates from interference of contributions from the current-current and photonic dipole ope…
