Investigating Bottom Quark Energy Loss, Hadronization, and B Meson Nuclear Modification Factors in B+ and BS0 Decays: Insights from CMS in pp, pPb, and PbPb Collisions by Mejia Jhovanny

“…The first is the pT -differential cross sections of BS0 and B+ mesons in pp collisions at 5.02 TeV. By utilizing previous PbPb collision data at the same nucleon-nucleon (NN) center of mass energy, RAA factors for the B mesons are determined. …”

B → J / ψ K (... by Mahboobeh Sayahi, Hossein Mehraban

“…We consider that J/ψ behaves as a light meson in compared to B meson. For B + → J / ψ K + ( 1270 ) and B + → J / ψ K + ( 1400 ) , experimental data of branching ratios are (1.8 ± 0.5) × 10−3 and <5 × 10−4, respectively. …”

Searching for heavy neutral leptons coupled to axion-like particles at the LHC far detectors and SHiP by Zeren Simon Wang, Yu Zhang, Wei Liu

“…We study ALPs produced from D- and B-meson decays via quark-flavor-violating couplings, and decaying exclusively into a pair of HNLs which mix with active neutrinos. …”

Study of B¯d,s⁎0→Dd,s+M- Decays with QCD Factorization Approach by Qin Chang, Xiaohui Hu, Zhe Chang, Junfeng Sun, Yueling Yang

“…In addition, associating with the relevant B meson decays, some interesting phenomena and relations are discussed in detail; for example, RB≡B(B¯q→Dq⁎P)/B(B¯q⁎→DqP)≃3τB/τB⁎, and fL,∥(B¯q→Dq⁎V)≃fL,∥(B¯q⁎→DqV).…”

Probing third-generation New Physics with K→πνν¯ and B→K(⁎)νν¯ by L. Allwicher, M. Bordone, G. Isidori, G. Piazza, A. Stanzione

“…We find that the slight excess observed in both channels supports the hypothesis of non-standard TeV dynamics of this type, as also hinted at by other B-meson decays, consistently with bounds from colliders and electroweak observables. …”

RAA and υn: Relativistic transport approach for charm and bottom toward a more solid phenomenological determination of Ds(T) by Sambataro Maria Lucia, Plumari Salvatore, Minissale Vincenzo, Parisi Gabriele, Greco Vincenzo

“…Within an event-by-event full Boltzmann transport approach followed by a hybrid hadronization via coalescence plus fragmentation, we investigate the extension to bottom quark dynamics discussing predictions for RAA and υ2,3 of B mesons comparing to the available experimental data by ALICE collaboration on electrons from B meson decay. …”

Study of b⟶c Induced B¯∗⟶Vℓν¯ℓ Decays by Qin Chang, Xiao-Lin Wang, Jie Zhu, Xiao-Nan Li

“…These decays involve much more helicity states relative to the corresponding B¯∗⟶Pℓ−ν¯ℓ and B¯⟶Vℓ−ν¯ℓ decays, and moreover, the contribution of longitudinal polarization mode (V meson) is relatively small, ~30%, compared with the corresponding B meson decays. We have also computed the branching fraction, lepton spin asymmetry, forward-backward asymmetry, and ratio RV∗L≡BB¯∗⟶Vτ−ν¯τ/BB¯∗⟶Vℓ′−ν¯ℓ′ℓ′=e,μ. …”

Effective theory approach to new physics with flavour: general framework and a leptoquark example by Marzia Bordone, Oscar Catà, Thorsten Feldmann

“…In this paper, we address this issue in view of the recently observed “flavour anomalies” in B-meson decays, which we take as a motivation to develop a general framework that allows us to systematically reduce the number of flavour parameters in the EFT. …”

Exclusive displaced hadronic signatures in the LHC forward region by Xabier Cid Vidal, Yuhsin Tsai, Jose Zurita

“…We show that the reconstruction of kaon vertices in narrow invariant mass windows can efficiently eliminate the combinatorial backgrounds from B-meson decays. While the same signal is extremely difficult to probe in the existing displaced jet searches at ATLAS/CMS, the LHCb search we propose can probe the branching ratio BR(h → SS) down to 0.1% (0.02%) level with 15 (300) fb−1 of data. …”

B ¯ → D ¯ D $$ \overline{B}\to \overline{D}D $$ decays and the extraction of f d /f u at hadron colliders by Jonathan Davies, Martin Jung, Stefan Schacht

“…Importantly, allowing in the same fit for the production fractions of charged and neutral B mesons to be different, we find f d /f u = 0.86 ± 0.05, which is 2.5σ away from unity, which, if confirmed, would have important phenomenological consequences.…”

Statistical production of Bc mesons in heavy-ion collisions at the LHC energy by Shouxing Zhao, Min He

“…We study the production of Bc mesons via c and bottom (b) quark recombination in a statistical fashion by placing Bc in the position of a member of the family of open b hadrons, which allows us to make quantitative predictions for the modifications of the production fraction (fc) of Bc mesons and its relative production to B mesons in sNN=5.02TeV Pb-Pb collisions with respect to proton-proton (pp) collisions at the same energy. …”
