Differential QE-like cross section dσ(E_QEν)/dQ^2_QE, in bins of E_QEν. Inner error bars show statistical uncertainties; outer error bars show total (statistical and systematic) uncertainty. The red histogram shows the MINERvA-tuned GENIE model used to estimate smearing and acceptance.

The much anticipated paper version of Cheryl Patrick’s thesis has been accepted by Physical Review D.   Check it out at:


The data release is available at


Update:  It is published in Phys. Rev. D which is now open access:


Cheryl Patrick successfully defended her thesis:

Measurement of the Antineutrino Double-Differential Charged-Current Quasi-Elastic Scattering Cross Section at MINERvA in March and is now a postdoc on SuperNEMO at University College London.

She came back to the US to give a fantastic Fermilab Wine and Cheese talk in June 2016 which has been written up in Fermi NewsWatch the video!

We went to the APS Division of Nuclear Physics conference in Vancouver BC in mid-October 2016.

Undergraduates Gabe Nowak and Evan Peters gave posters on their work and PI Heidi Schellman gave a 10 minute talk explaining anti-neutrino quasi-elastic scattering.

Evan’s poster was placed with theoretical posters presented by students also working on neutrino scattering, leading to much discussion amongst the neutrino community.

Much homework was done during the 9 hour drive back in the rain. Next time I will bring two flashlights in the car.

Welcome to Mateus Fernandes Carneiro who has joined the Schellman neutrino group as a postdoctoral scholar.  Mateus just completed his dissertation “Measurement of Muon Neutrino Quasi-Elastic Scattering on a Hydrocarbon Target at Enu of 6 GeV” at the Centro Brasileiro de Pesquisas Fisicas using the MINERvA neutrino detector at Fermilab.  He will be working with Heidi Schellman and Amit Bashyal on studies of neutrino cross sections.  Mateus will be working from Fermilab most of the time but will visit us frequently.

Gabriel Nowak is a Junior in the Physics program at Oregon State.  He’s been in the Schellman group for 6 months and is writing a data comparator for the MINERvA and MicroBooNE experiments at Fermilab.

This link compares two versions of the MINERvA simulation code.  It combines  the CDF data validation code with Gabriel’s histogram generator.

We just posted our new postdoctoral scholar position.  The location is most likely Fermilab but we’ll consider people interested in working in Corvallis.


MicroBooNE/MINERvA (AJO-5824)

Oregon State U. – Postdoc

Field of Interest: hep-ex, nucl-ex
Experiment: FNAL-E-0974, FNAL-E-0938
Deadline: 2015-10-01
Region: North America
Job description:
Oregon State University is seeking a postdoctoral scholar to participate in the MicroBooNE and MINERvA experiments at Fermilab. The Oregon State group’s expertise is in data handling, validation and algorithms and our physics interest is in precision measurements of neutrino cross section in the energy regimes relevant to future neutrino oscillation experiments. The position will most likely be at Fermilab in Illinois.

We are looking for someone with prior experimental experience in either high energy physics or nuclear physics, not restricted to neutrino physics. Significant expertise in modern scientific computing and data analysis is a plus.

For full consideration, please apply by 10/1/2015

Brandon Walker graduated from Northwestern in 2010 with Bachelor’s degrees in Physics and Astronomy and in Mathematics.  He did his honors thesis in the Schellman group on `An Algorithm for Particle Tracking and Analysis of Muons in the Main Injector Experiment v-A (MINERvA).”


He is currently a doctoral student in Medical Physics at the University of Wisconsin at Madison.

For his PhD, he’s designing and building a modular multi-source electron beam scanner for high speed computed tomography and 3D printing applications. The system would enable ultra-fast CT scans for improved image quality in cardiac imaging and could be a game changer for 3D printing. The Wisconsin Alumni Research Foundation (WARF) has filed two patents for the project, one in 2014 and another in 2015 (patents pending).

He has also co-founded 2 startup companies. Formula Database, GelCombs and has his own consulting company that does quality assurance for radiation and diagnostic imaging products.



Emily Maher, a Physics Professor at MCLA, who was doing the night shift, has kindly documented the official setup in the Fermilab control room. This is on the MINERvA shift wiki but that makes it hard to post pictures so I’m reposting here.
