Time-dependent \g/$\phi_3$ measurements by Babar 。
CP Violation Results from B Decays at BaBar 。
This paper intends to shortly summarize the recent results on Spectroscopy, published from the BABAR Collaboration. The BABAR experiment is a B-factory, at SLAC, where asymmetric energy beams of elect...
Experimental data from the PEP-II B-factory at 10.6 GeV center-of-mass (c.m.) energy, obtained via initial-state radiation (ISR) with the BABAR detector, are presented. The cross sections for many had...
Precise measurement of the e+e－→π+π－(γ) cross section with the initial state radiation method at BABAR
pion form factor ISR g-2 BABAR
2010/5/7
We present a precise BABAR measurement on the cross section of the process e+e－→π+π－(γ) from threshold to an energy of 3 GeV with the initial state radiation (ISR) technique, using 232 fb－1 of data co...
D0D0 mixing and other recent charm results from BABAR
mixing oscillations charm meson spectroscopy
2010/5/7
Studies in which BABAR data have shown evidence for mixing in the neutral charm meson system are presented. A new measurement of the lifetime difference parameter yCP=(1.16±0.22±0.18)% is described. R...
Measurements of the γγ*→π0 and γγ*→ηc transition form factors at BABAR
two-photon interaction pseudoscalar meson transition form factor pi0 eta eta(958) etac
2010/5/7
We present measurements of the γγ*→π0 transition form factor for the momentum transfer range Q2=4—40 GeV2 and the γγ*→ηc transition form factor for the range Q2=2—50 GeV2. The current status of measur...
BABAR measurement of baryon time-like form factors via initial state radiation
baryon form factor Initial state radiation BABAR
2010/5/7
BABAR has measured with unprecedented accuracy the e+e－→pp and e+e－→ΛΛ cross sections by means of the initial state radiation technique, which has the advantages of good efficiency, good energy resolu...
The BABAR experiment has now completed data taking and with an integrated luminosity of
531 fb1 of e+e collision data has recorded some 480 million tau-pair events. Various studie...
