Annihilation-Type Semileptonic B-Meson Decays

EPJ Web of Conferences, 2017
The rare semileptonic decay B0 → ϕℓ+ℓ−, where ℓ is an electron or muon, is considered in the QCD Factorization approach. The differential branching fraction, partially integrated over the interval q2 = [1 GeV2, 8 GeV2] of dilepton invariant mass squared,

Fractional Pebbling and Thrifty Branching Programs

, 2009
We study the branching program complexity of the {\em tree evaluation problem}, introduced in \cite{BrCoMcSaWe09} as a candidate for separating \nl\ from\logcfl. The input to the problem is a rooted, balanced $d$-ary tree of height$h$, whose internal nodes are labelled with $d$-ary functions on$[k]=\{1,\ldots,k\}$, and whose leaves are labelled with ...

Study of B → Xγ decays and determination of |V_(td)/V_(ts)| [PDF]

, 2010
Using a sample of 471×10^6 BB̅[overbar] events collected with the BABAR detector, we study the sum of seven exclusive final states B→X_(s(d))γ, where X_(s(d)) is a strange (nonstrange) hadronic system with a mass of up to 2.0 GeV/c^2.

Observation of the decay B s 0 → K 0 p p ¯ $$ {B}_s^0\to {K}^0p\overline{p} $$ and measurement of the B s 0 → K 0 p p ¯ $$ {B}_{(s)}^0\to {K}^0p\overline{p} $$ branching fractions

Journal of High Energy Physics
A study of the charmless baryonic decays B s 0 → K 0 p p ¯ $$ {B}_{(s)}^0\to {K}^0p\overline{p} $$ is presented, where B s 0 $$ {B}_{(s)}^0 $$ denotes either a B 0 or a B s 0 $$ {B}_s^0 $$ meson.

Search for the charmed pentaquark candidate Θ_c(3100)^0 in e^+e^- annihilations at √s=10.58 GeV [PDF]

, 2006
We search for the charmed pentaquark candidate reported by the H1 collaboration, the Θ_c(3100)^0, in e^+e^- interactions at a center-of-mass (c.m.) energy of 10.58 GeV, using 124 fb^(-1) of data recorded with the BABAR detector at the PEP-II e^+e ...

Branching Fractions of the $X(3872)$

, 2019
The recoil momentum spectrum from the decay $B^+ \to K^+ +\mathrm{anything}$ has recently been measured by the BaBar collaboration. The spectrum has a peak with invariant mass near the mass of the $X(3872)$ meson. The preliminary measurement by the BaBar collaboration implies that its branching fraction into $J/ \, ^+ ^-$ is about 4\%. We emphasize

Observation of ψ(3686) → Ξ − K S 0 Ω ¯ + $$ {\Xi}^{-}{K}_S^0{\overline{\varOmega}}^{+} $$ + c.c.

Journal of High Energy Physics
Using a sample of (2.712 ± 0.014) × 109 ψ(3686) events collected with the BESIII detector at the electron positron collider BEPCII, the decay ψ(3686) → Ξ − K S 0 Ω ¯ + $$ {\Xi}^{-}{K}_S^0{\overline{\varOmega}}^{+} $$ + c.c. is observed for the first time,

Higgs Branching Fraction Study in ILC

, 2012
Precise measurement of the Higgs boson properties are important issues for the International Linear Collider (ILC) project to understand the particles mass generation mechanism which strongly related to the coupling with the Higgs boson. Large Hadron Collider (LHC) experiments exclude the large area of the predicted Higgs mass region and their results ...

Observation of χ cJ J = 0 1 2 → p p ¯ ηη $$ {\chi}_{cJ}\left(J=0,1,2\right)\to p\overline{p}\eta \eta $$

Journal of High Energy Physics
Using (2712.4 ± 14.3) × 106 ψ(3686) candidates collected by the BESIII detector operating at the BEPCII storage ring, the decays χ cJ J = 0 1 2 → p p ¯ ηη $$ {\chi}_{cJ}\left(J=0,1,2\right)\to p\overline{p}\eta \eta $$ are observed for the first time ...
