Research and Professional Experience
Physics Data Analysis

(< 50 citations); the analysis team was composed of 3 physicists.
– CDF Collaboration: Primary author, search for a cascade pentaquark, my talk at DIS 2004 [20]
(< 50 citations) and Phys. Rev. D paper [18] (< 50 citations); the analysis team was composed
of 3 physicists.
– CDF Collaboration: Primary author, discovery of four bottom baryon resonant states,
+
+
specifically J P = 12 states Σb− , Σb+ and J P = 32 states Σb∗− , Σb∗+ , reported at the conferences [16] and published as Phys. Rev. Lett. paper [15] (100+ citations); the analysis team
was composed of 5 physicists from UNM, Johns Hopkins and FNAL.
– CDF Collaboration: Primary author, confirmation, precise mass and width measurements
of four bottom baryon resonant states, Σb− , Σb+ and Σb∗− , Σb∗+ ; the analysis team was composed of 2 physicists. The results were reported at the ICHEP 2010 Conference [10]
and published as a Phys. Rev. D paper [9] (< 50 citations). The measurement results
have been entered by Particle Data Group (PDG) into the Σb bottom-baryon record and
the Σb∗ bottom-baryon record. The Ph.D. Thesis by Dr. Constantinos Calancha (CIEMAT,
Spain) is based on this result.
– CDF Collaboration: Primary author, the observation of an orbitally excited bottom baryon
Λ∗0
b ; the analysis team was composed of 2 physicists. The result was reported at the the
ICHEP 2012 Conference [6] and published as a Phys. Rev. D paper [5] (< 50 citations).
The measurement result has been entered by Particle Data Group (PDG) into
the Λ∗0
b (5920) bottom baryon record. The Ph.D. Thesis by Dr. Prabhakar Palni (UNM) is
based on this result.
– ATLAS Collaboration: leading the ongoing analysis on the measurement of the relative crosssections σ(W + D(∗) )/σ(W ) and σ(Z 0 + D(∗) )/σ(Z 0 ), where W and Z 0 are reconstructed
in their electron and muon channels and the charm is reconstructed as exclusive D-meson
states, e.g. D∗+ → D0 (→ K − π + )πs+ , D+ → K − π + π + . The analysis is being done by a
team of 3 senior physicists and 3 graduate students from LBNL, UNM and from Univ. of
Tokyo. I am the chair of the analysis group, I convene bi-weekly meetings of the group.
3
The meetings are an effective forum, in which I lead discussions and mentor the graduate
students, T. Okuyama (Univ. of Tokyo), Y. Ninomiya (Univ. of Tokyo) and Neil McFadden
(UNM). The production of W + D(∗) states is directly sensitive to an s-quark PDF at a
momentum transfer squared of Q2 ∼ m2W and a momentum fraction x ∈ (0.001, 0.1). The
ratio Rc± = σ(W + + D(∗)− )/σ(W − + D(∗)+ will also be measured with a high statistical
uncertainty to evaluate the symmetry of the light-quark sea, rs = 0.5(s + s)/d and the relative
strange-quark asymmetry Ass = (s − s)/s. The Z 0 + D(∗) production is probing directly
the c- or b-quark PDFs again at (x, Q2 ) ∼ (0.001...0.1, m2Z ). The powerful high statistics
signal of D(∗) associated with Z 0 has been found contrary to a low statistics signals published
recently by LHCb. Many signals for new physics at LHC involve W, Z 0 bosons and hadron
states containing heavy quarks c and b. Moreover the W/Z 0 + Q processes are the important
physical background to the Higgs produced in W/Z 0 + H(→ bb) and identified in its most
abundant hadronic mode when the candidate event can be triggered by a fast lepton coming
from W ± → ℓνℓ and Z 0 → ℓ+ ℓ− . The process gb → Z 0 b is an irreducible background to
gb → Hb, where the Z 0 boson and the H boson decay to the same final state bb, τ + τ − , µµ.
The analysis group is currently developing an MVA approach to measure the b-quark
√fraction of
D(∗) observed yields. Both analysis topics are based on a large dataset collected at s = 8 TeV
by the ATLAS detector during 2012 runs.
