CP violation induced by the double resonance for pure annihilation decay process in perturbative QCD

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In a perturbative QCD approach we study the direct CP violation in the pure annihilation decay process of $$\bar{B}^0_{s}\rightarrow \pi ^+\pi ^-\pi ^+\pi ^-$$ B ¯ s 0 → π + π - π + π - induced by the $$\rho $$ ρ and $$\omega $$ ω double resonance effect.

Using an amplitude analysis to measure the photon polarisation in $$B \rightarrow K\pi \pi \gamma $$ B→Kππγ decays

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
A method is proposed to measure the photon polarisation parameter $$\lambda _{\gamma }$$ λγ in $${{b}} \!\rightarrow {s} {\gamma } $$ b→sγ transitions using an amplitude analysis of $$B\!\rightarrow K\pi \pi {\gamma } $$ B→Kππγ decays.

Rancang Bangun Sistem Kontrol Keamanan Gerbang Menggunakan Raspberry Pi B+ Berbasis Web

open access: yesJournal CERITA, 2021
Computer and information technology from time to time are always experiencing developments, both in terms of hardware, software and the internet being one of the most important things atthis time. The increasing number of applications of computer technology will make the role of computers increasingly important to be more advanced (modernization).

Study of B -> p<(p)over bar>pi pi

open access: yes, 2020
Using a data sample of 772 x 10(6) B (B) over bar pairs collected on the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric energy e(+)e(-) collider, we report the observation of B-0 -> p (p) over bar pi(+)pi(-) and the first ...

Branching fractions and CP asymmetries in B-0 ->pi(0)pi(0), B+->pi(+)pi(0), and B+-> K+pi(0) decays and isospin analysis of the B ->pi pi system [PDF]

open access: yes, 2005
Based on a sample of 227x10(6) B(B) over bar pairs collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, we measure the branching fraction B(B-0&RARR;π(0)π(0))=(1.17&PLUSMN; 0.32&PLUSMN; 0.10)x10(-6), and the asymmetry ...
