Book excerpt: The BABAR detector, operating at the SLAC PEP-II asymmetric B Factory, has collected a sample of 32 million B[bar B] pairs by May 2001, at energies close to the[Upsilon](4S) resonance. The measurement of sin2[beta]= 0.59[+-] 0.14(stat)[+-] 0.05(syst), performed with a study of time-dependent CP-violating asymmetries in neutral B decays, establishes CP violation at the 4[sigma] level. In addition, preliminary results on CP-violating asymmetries in the decay channel B[sup 0][yields][pi][sup+][pi][sup -] are presented.

Book excerpt: In the present paper we review recent experimental results from the BABAR experiment concerning the measurement of the CKM angles. A particular highlight is given to the novel independent determination of the angle [alpha] from B° → a1(1260){sup {+-}}[pi]{sup {-+}} and to the recent full-luminosity updates of several angle [gamma] measurements.

Available in PDF, EPUB and Kindle. Book excerpt: The BABAR detector at the PEP-II asymmetric B Factory at SLAC collected a sample of 23 x 10[sup 6] B[bar B] pairs in the years 1999 and 2000. Using this data sample, we measure the amplitude of the time-dependent CP-violating asymmetry in neutral B decays to the CP eigenstates J/[psi] K[sub S][sup 0], [psi](2S) K[sub S][sup 0] and J/[psi] K[sub L][sup 0]. We find a value of sin2[beta]= 0.34[+-] 0.20(stat)[+-] 0.05(syst). We also present preliminary measurements of the B[sup 0][bar B][sup 0] oscillation frequency and of the lifetimes of charged and neutral B mesons.

Book excerpt: The BABAR detector, operating at the SLAC PEP-II asymmetric B Factory, has collected a sample of 32 million B{bar B} pairs by May 2001, at energies close to the?(4S) resonance. The measurement of sin2? = 0.59 ± 0.14(stat) ± 0.05(syst), performed with a study of time-dependent CP-violating asymmetries in neutral B decays, establishes CP violation at the 4? level. In addition, preliminary results on CP-violating asymmetries in the decay channel B° →??− are presented.

Download or read book BaBar Explores CP Violation written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: We present results on time-dependent CP asymmetries in neutral B decays. The measurements use 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. We study events in which one neutral B meson is fully reconstructed in a final state and the other B meson is determined to be either a B[sup 0] or[bar B][sup 0] from its decay products. Final states considered include B[sup 0][yields] J/[psi]K[sub S][sup 0], B[sup 0][yields] J/[psi]K[sub L][sup 0], B[sup 0][yields] J/[psi][pi][sup 0], B[sup 0][yields] D*[sup+] D*[sup -], B[sup 0][yields][phi]K[sub S][sup 0], B[sup 0][yields][pi][sup+][pi][sup -], and B[sup 0][yields][rho][sup[+-]][pi][sup[-+]].

This book was released on 2001-09-25 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers the first strong evidence of the existence of CP violation in neutral B decays extracted from sophisticated B factories in the US and Japan. It also holds out the expectation of rare B decays and D, K physics in the near future. In addition, new physics beyond the Standard Model is described. Both experimental and theoretical points of view are given.

Book excerpt: Results of recent searches for new physics in CP violation in charm decays from the BABAR experiment are presented. These results include a measurement of D0 - anti D0 mixing and searches for CP violation in two-body D0 decays, a search for CP violation in the charm decays D" 2!KS0K " and D s" 2!KS0K", KS0[pi]", and a search for direct CP violation in the singly-Cabibbo suppressed D" 2!K+K-[pi]"decays. These studies are based on the fi nal dataset collected by BABAR at the PEP-II B factory at SLAC in the period 1999-2008. No evidence of CP violation is found in these charm decays. The measured mixing parameter yCP = [0.72 " 0.18(stat) " 0.12(syst)]% excludes the no-mixing null hypothesis with a signifi cance of 3.3[sigma].

Download or read book First CP Violation Results from BABAR. written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a preliminary measurement of time-dependent CP-violating asymmetries in B[sup 0][yields] J/[psi]K[sub s][sup 0] and B[sup 0][yields][psi](2S)K[sub s][sup 0] decay recorded by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. The data sample consists of 9.0 fb[sup -1] collected at the[Upsilon](4S) resonance and 0.8 fb[sup -1] off-resonance. One of the neutral B mesons, produced in pairs at the[Upsilon](4S), is fully reconstructed. The flavor of the other neutral B meson is tagged at the time of its decay, mainly with the charge of identified leptons and kaons. The time difference between the decays is determined by measuring the distance between the decay vertices. Wrong-tag probabilities and the time resolution function are measured with samples of fully-reconstructed semileptonic and hadronic neutral B final states. The value of the asymmetry amplitude, sin2[beta], is determined from a maximum likelihood fit to the time distribution of 120 tagged B[sup 0][yields] J/[psi]K[sub s][sup 0] and B[sup 0][yields][psi](2S)K[sub s][sup 0] candidates: sin2[beta]= 0.12[+-] 0.37 (stat)[+-] 0.09 (syst).

Book excerpt: The BABAR collaboration has analyzed 60M B[bar B] pairs collected at the[Upsilon](4S) resonance at the PEP II asymmetric collider at SLAC. Using this data sample they have measured the CP violation parameters sin(2[beta])= 0.75[+-] 0.09[sub STAT][+-] 0.04[sub SYST] and[lambda]= 0.92[+-] 0.06[sub STAT][+-] 0.02[sub SYST] from B[sup 0][yields] c[bar c]+ K[sup 0(*)]+ c.c. decays. From charmless 2-body B decays they measure A[sub K[pi]]= -0.05[+-] 0.06[+-] 0.01( -0.14,+0.05), S[sub[pi][pi]]= -0.01[+-] 0.37[+-] 0.07( -0.66,+0.62), C[sub[pi][pi]]= -0.02[+-] 0.29[+-] 0.07( -0.54,+0.48).
