Phenomenology of inclusive $B ˉ \to X_{s} ℓ^{+} ℓ^{-}$ for the Belle II era

Tobias Huber, Tobias Hurth, Jack Jenkins +3

With the first data being recorded at Belle II, we are at the brink of a new era in quark flavour physics. The many exciting new opportunities for Belle~II include a full angular a…

Signatures of a Flavor Changing $Z^{'}$ Boson in $B_{q} \to γ Z^{'}$

Shao-Long Chen, Amit Dutta Banik, Zhaofeng Kang +2

Rare $B$ meson decays offer an opportunity to probe a light hidden $Z^{'}$ boson. In this work we explore a new channel $B_{q} \to γ Z^{'}$ ( $q = d, s$ ) followed by a cascade decay of $Z^{'}$ …

Long distance effects in inclusive rare $B$ decays and phenomenology of $B ˉ \to X_{d} ℓ^{+} ℓ^{-}$

Tobias Huber, Tobias Hurth, Jack Jenkins +3

Rare inclusive $B$ decays such as $B ˉ \to X_{s (d)} ℓ^{+} ℓ^{-}$ are interesting probes for physics beyond the Standard Model. Due to the complementarity to their exclusive cou…

Heavy neutrino searches at future $Z$ -factories

Jian-Nan Ding, Qin Qin, Fu-Sheng Yu

We analyze the capacity of future $Z$ -factories to search for heavy neutrinos with their mass from 10 to 85 GeV. The heavy neutrinos $N$ are considered to be produced via the proce…

$Z \to π^{+} π^{-}, K^{+} K^{-}$ : A touchstone of the PQCD approach

Shan Cheng, Qin Qin

We study two rare decays, $Z \to π^{+} π^{-}$ and $K^{+} K^{-}$ , in the perturbative QCD approach up to the next-to-leading order of the strong coupling and the leading power of $1/ m_{Z}$ , $m_…

Prospects of discovering stable double-heavy tetraquarks at a Tera- $Z$ factory

Ahmed Ali, Alexander Ya. Parkhomenko, Qin Qin +1

Motivated by a number of theoretical considerations, predicting the deeply bound double-heavy tetraquarks $T_{[u ˉ d ˉ]}^{{bb}}$ , $T_{[u ˉ s ˉ]}^{{bb}}$ and $T^{\{b…
