First Observation of Bottom Baryon Σb States at CDF
نویسنده
چکیده
We present the latest results on the search for bottom baryon states Σb using ∼ 1 fb of CDF data. The study is performed with the world’s largest sample of fully reconstructed Λb decays collected by CDF II detector at √ s = 1.96TeV in the hadronic trigger path. We observe 4 new states consistent with Σ (∗)± b bottom baryons.

Heavy Flavor Baryon States at the Tevatron
Precision measurements of the masses and widths of the bottom baryon resonances Σb and Σb* and charm baryons Λc(2595), Λc(2625), Σc(2455), and Σc(2520) are reported. A new measurement of Λb production is described. The studies include the first measurement of the widths and isospin mass splittings of the members of the Σb family. The charm baryons are examined through their strong decays ...

We present recent CDF results based on approximately 1 fb −1 of p¯ p collisions at √ s = 1.96 TeV delivered at Fermilab Tevatron. Results shown include the observation of the Bs oscillation frequency, the first observation of bottom baryon Σ (*)± b states, updates on B hadrons lifetimes, and searches for rare decays in the b → sµ + µ − transition and in charmless two-body B decays.

متن کاملLatest Results on Bottom Spectroscopy and Production with CDF
Using data collected with the CDF Run II detector, new measurements on bottom production cross-sections are presented. The latest achievements in bottom hadron spectroscopy are discussed. The results are based on a large sample of semileptonic and hadronic decays of bottom states made available by triggers based on the precise CDF tracking system. 1 First Observation of the Baryons Σb and Σ ∗ b...
