This dissertation presents a measurement of CP asymmetries and branching fractions for neutral B meson decays to two-body final states of charged pions and kaons. The results are obtained from a data sample of about 88 million?(4S) → B{bar B} decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B factory located at the Stanford Linear Accelerator Center.

We present measurements of branching fractions and CP-violating asymmetries for neutral B meson decays to two-body final states of charged pions and kaons. The results are obtained from a data sample of about 88 million[Upsilon](4S)[yields] B[bar B] decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. From a time-independent fit we measure the charge-averaged branching fractions[Beta](B[sup 0][yields][pi][sup+][pi][sup -])= (4.7[+-] 0.6[+-] 0.2) x 10[sup -6] and[Beta](B[sup 0][yields] K[sup+][pi][sup -])= (17.9[+-] 0.9[+-] 0.7) x 10[sup -6], where the first uncertainty is statistical and the second is systematic; the 90% confidence level upper limit[Beta](B[sup 0][yields] K[sup+]K[sup -])

Download Measurement of Branching Fractions and Search for CP-violating Charge Asymmetries in Charmless Two-body B Decays Into Pions and Kaons Book in PDF, ePub and Kindle
We present measurements of the branching fractions and a search for CP-violating charge asymmetries in charmless hadronic decays of B mesons into two-body final states of kaons and pions. The results are based on a data sample of approximately 23 million BB(bar) pairs collected by the BABAR detector at the PEP-II asymmetric B Factory at SLAC.

The authors present measurements of branching fractions and CP-violating asymmetries in decays of B mesons to two-body final states containing a K[sup 0]. The results are based on a data sample of approximately 88 million [Upsilon](4S) [yields] B[bar B] decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC.

The most recent results obtained by the BABAR experiment at the PEP-II asymmetric-energy B Factory at SLAC on CP-violating asymmetries and branching fractions for neutral and charged B decays are presented here. The analysis was performed on a data sample of[approx] 88 million[Upsilon](4S)[yields] B[bar B] decays collected between 1999 and 2002. Using b[yields] c[bar c]s decays, we measure sin2[beta]= 0.741[+-] 0.067(stat)[+-] 0.034(syst). We also present sin2[beta] measurements from, b[yields] s[bar s]s and b[yields] c[bar c]d processes. From neutral B meson decays to two-body final states of charged pions and kaons, we derive for the CP violating parameters, S[sub[pi][pi]]= 0.02[+-] 0.34[+-] 0.05[-0.54,+0.58] and C[sub[pi][pi]]= -0.30[+-] 0.25[+-] 0.04[-0.72,+0.12]. First results for B[yields][pi][sup+][pi][sup -][pi][sup 0] and K[sup[+-]][pi][sup[-+]][pi][sup 0] final states dominated by the[rho][sup[+-]] resonance, are also presented.
