Accurate Determination of the Neutron Skin Thickness of through Parity-Violation in Electron Scattering

We report a precision measurement of the parity-violating asymmetry A PV in the elastic scattering of longitudinally polarized electrons from Pb 208. We measure A PV= 550±16 (stat)±8 (syst) parts per billion, leading to an extraction of the neutral weak form factor F W (Q 2= 0.00616 GeV 2)= 0.368±0.013. Combined with our previous measurement, the extracted neutron skin thickness is R n− R p= 0.283±0.071 fm. The result also yields the first significant direct measurement of the interior weak density of Pb 208: ρ W 0=− 0.0796±0.0036 (exp)±0.0013 (theo) fm− 3 leading to the interior baryon density ρ b 0= 0.1480±0.0036 (exp)±0.0013 (theo) fm− 3. The measurement accurately constrains the density dependence of the symmetry energy of nuclear matter near saturation density, with implications for the size and composition of neutron stars.

Precision measurement of the weak charge of the proton

The Qweak experiment has made possible the first determination of the weak charge of the proton QWp by incorporating earlier parity-violating electron scattering (PVES) data at higher Q2 to constrain hadronic corrections. The value of QWp obtained in this way is QWp(PVES)=0.0719±0.0045, which is in good agreement with the standard model prediction of QWp(SM)=0.0710±0.0007.

Measurement of parity violation in electron–quark scattering

The experiment provides a measurement of the parity-violating asymmetry in electron–quark scattering, which yields a determination of $2C_{2u} − C_{2d}$ (where u and d denote up and down quarks, respectively) with a precision increased by a factor of five relative to the earlier result. These results provide evidence with greater than 95 percent confidence that the C2q couplings are non-zero, as predicted by the electroweak theory.

Measurement of the Neutron Radius of 208Pb Through Parity-Violation in Electron Scattering

The skin thikness of 208Pb, difference between the radii of the neutron and proton distributions Rn - Rp = 0.33 +0.16 -0.18 fm and provides the first electroweak observation of the neutron skin which is expected in a heavy, neutron-rich nucleus.

CosmicPi: Building the world’s largest distributed cosmic ray detector

I’m collaborating with a group of people from CERN to build the world’s largest open source distributed cosmic ray telescope. We are using our spare time to build Cosmic Pi, a cosmic ray detector based on a Raspberry Pi. The goal is to crowdsource the world’s largest cosmic ray telescope by getting the devices into the hands of people and organisations around the globe and then collecting data that will help astrophysicists understand more about cosmic rays.

The CosmicPi detector aims to fulfill the following features:

• Detects cosmic muons and shares the events on the internet
• All contained in a small, pocket sized box.
• Low-cost at a \$350 budget
• Capable of detecting Muons of cosmic origin, mean energy 2.4 GeV using an organic plastic scintillator.
• Fitted with a GPS receiver, altitude sensor, accelerometer and magnetometer to locate cosmic rays in time and space with high precision.
• Accessible over Wi-Fi via a web-interface.
• Open source in all aspects

Volunteering for Hour of Code

It is vital to have a globally competitive STEM workforce in the USA. I’m committed to volunteer at public schools and other outreach programs to teach computer science related subjects for students at all ages. Volunteering for the Hour of Code during December 5-11, 2016 at the Lincoln Preparatory School, Grambling, LA

Volunteering my time for Adopt-a-Physicist program organized by Sigma Pi Sigma society at APS. It connects high school students to real physics graduates and PI has been volunteering for this program for three years and will continue to participate. I have been volunteering for four years now.
