Analysis of rho - omega interference in the pion form - factor
The formalism underlying the analysis of e + e − → π + π − in the ρ − ω interference region is carefully revisited. We show that the standard neglect of the pure I = 0 omega, ω I , " direct " coupling to ππ is not valid, and extract those combinations of the direct coupling and ρ-ω mixing allowed by experiment. The latter is shown to be only very weakly constrained by experiment , and we conclu...
متن کاملPeriodic Interference Structures in the Timelike Proton Form Factor.
An intriguing and elusive feature of the timelike hadron form factor is the possible presence of an imaginary part associated to rescattering processes. We find evidence of that in the recent and precise data on the proton timelike form factor measured by the BABAR Collaboration. By plotting these data as a function of the 3-momentum of the relative motion of the final proton and antiproton, a ...
متن کاملGingival Thickness Assessment: Visual versus Direct Measurement
Background and Aim: Several methods have been suggested to measure gingival thick-ness. This study aimed to assess the reliability of visual assessment of facial gingival biotype of maxillary and mandibular teeth with or without using a periodontal probe in comparison with direct measurement. Materials and Methods: Sixty-seven healthy patients (25 women and 42 men) with a total of 100 hopele...

متن کاملDistinguishing Direct versus Indirect Transcription Factor-DNA Interactions
Transcriptional regulation is largely enacted by transcription factors (TFs) binding DNA. Large numbers of TF binding motifs have been revealed by ChIP-chip experiments followed by computational DNA motif discovery. However, the success of motif discovery algorithms has been limited when applied to sequences bound in vivo (such as those identified by ChIP-chip) because the observed TF-DNA inter...
