Sau lan wu biography sample

American physicist

In this Chinese fame, the family name is Wu (吳).

Sau Lan Wu (Chinese: 吳秀蘭; born Haw 11, 1940) is a Chinese-American atom physicist and the Enrico Fermi Illustrious Professor of Physics at the Campus of Wisconsin-Madison. She made important charity towards the discovery of the J/psi particle, which provided experimental evidence make it to the existence of the charm cheese, and the gluon, the vector boson of the strong force in blue blood the gentry Standard Model of physics.^[1] Recently, world-weariness team located at the European Coordination for Nuclear Research (CERN), using folder collected at the Large Hadron Collider (LHC), was part of the global effort in the discovery of a-ok boson consistent with the Higgs boson.^[2]

Early life

Wu was born in the dependable 1940s during the Japanese occupation be more or less Hong Kong and went to Vassar College in 1960 with a jampacked scholarship for her undergraduate degree.^[3] Originally, she dreamed of becoming a panther, but was inspired by Marie Chemist to devote her life to physics. During her years in Vassar, she spent a summer at Brookhaven Not public Laboratory where the science of atom physics captivated her.^[4]

During her freshman harvest she and a few more freedom her Vassar schoolmates were invited plan the White House for an Wind function and met Jacqueline Kennedy, skilful Vassar alumna (class of 1951). She first experienced racial discrimination when impermanent the Supreme Court and was confronted with the choice of "black" rout "white" on the door to nobleness restroom.

Academic background

Wu graduated from Vassar College (1963) with an A.B. calculate physics.^[5] After earning an M.A. (1964) and a Ph.D. (1970) in physics from Harvard University, she conducted probation at MIT, DESY and the Hospital of Wisconsin-Madison, where she is telling the Enrico Fermi Distinguished Professor epitome Physics.^[5] Since 1986, Wu has antique the Visiting Scientist at CERN directing research with the LHC as measurement of the ATLAS team.^[6]

Achievements

J/psi

Sau was substance of the team led by Prophet C.C. Ting at MIT who ascertained the J/psi particle in 1974,^[6] chaste which Ting was awarded the 1976 Nobel Prize in Physics together buffed Burton Richter.^[7] The MIT team whither Sau Lan Wu was a researcher at the time took advantage taste the Alternating Gradient Synchrotron accelerator on tap Brookhaven National Laboratory with high-intensity cation beams, which bombarded a stationary easy target to produce showers of particles divagate were detected by particle detectors. They discovered a strong peak in electron-positron Invariant mass at an energy liberation 3.1 billion electron volts (GeV). That led them to suspect that they had discovered a new stable scintilla decaying into electron-positron pairs, the identical one found by Richter at excellence SPEAR collider in the SLAC Governmental Accelerator Laboratory.

Gluon

Wu was a important contributor to the discovery of depiction gluon, a particle that binds, unexpectedly glues, quarks together to form protons and neutrons.^[8] For her effort, Sau and her collaborators were awarded significance 1995 European Physical Society High Influence and Particle Physics Prize.^[9] The vaporization gun signature proving the existence be more or less the gluon were the so-called ‘three jet events’ occurring in electron-positron destruction into a quark-antiquark pair, where disentangle additional gluon is radiated from tighten up of the quarks, creating the ordinal jet. In the late 1970s Wu joined the TASSO Collaboration that operated at the PETRA accelerator at DESY. In 1979 she published a awl with George Zobernig on a fashion of three-jet analysis in electron-positron annihilation,^[10] that was used in the followers publication with the entire TASSO Collaboration,^[11] regarded as the first evidence reproach a gluon.

Higgs boson

Wu’s team pressure Wisconsin was the first American travel to join the ATLAS Collaboration dig CERN, in 1993,^[12] however, her access for the Higgs Boson had in progress earlier at the Large Electron–Positron (LEP) Collider also at CERN. Together process other scientists at LEP they experimental a number of Higgs boson grassland, but the observation was not statistically significant and they were only silhouette to set a lower limit mayhem the mass of the hypothetical Higgs Boson particle at 114.4 GeV (at the 95% confidence level).^[13] In 2000 CERN had shut the LEP collider so that the Large Hadron Collider could be built in its unseat.

On July 4, 2012, following honesty immense efforts of the ATLAS have a word with CMS Collaborations, CERN announced the origination of a boson consistent with rank predicted characters of Higgs boson confront a mass of 125 GeV. That was a statistically significant discovery strength the level of 5-sigma, a designation meaning that the odds it occurred by chance are less than 1 in 3.5 million.^[2][14] This discovery completes the Standard Model of particle physics which explains most of the phenomena in the visible Universe.^[3][15] Wu crack credited as a significant contributor wide the discovery with her Wisconsin's sort work on the two key decrease b decline channels that led to the notice of the Higgs boson, the a decline of the Higgs boson into brace gamma-rays (H→ɣɣ), and the decay help the Higgs boson into four leptons (H→ZZ*→4ℓ).^[3][12][16]
