NuSTEC

Welcome to the NuSTEC school 2017 webpage!

The program will include 33 hours of lectures and 12 hours of recitation encouraging questions and discussion on all of the day’s lectures. The aim of the program is to provide the necessary theoretical background on the physics of electroweak interactions with nucleons and nuclei. It should allow the participants to understand recent developments and to contribute to this field, which has become very important for the future of neutrino physics. Although this training is ideally suited for experimental and theoretical advanced graduate students and young postdocs, senior researchers may find these lectures informative and are welcome to participate.

 

 

Everyday, there is a dedicated recitation session. Students are encouraged to ask questions and discuss on all of the day’s lectures with lecturers.

    Very brief recap of T2K and NOVA detectors and description of the oscillation analyses in the two experiments. Then we will try to answer to the following questions:
    -how the uncertainties on neutrino-nucleus scattering enter in the oscillation game?
    -how can we test the sensitivity of our analyses to such uncertainties?
    -what do we need to measure to improve the cross-section systematics in the determination of the oscillation parameters?
    And, if time permits, we will make a short excursion into the future: what will be the
    impact of such systematics in DUNE and Hyper-Kamiokande?

12. Generators

     

    

    12.1. Monte Carlo methods and event generators (3 hours)

    Dr. Tomasz Golan (Univ. Wroclaw, Poland)

    The lectures start with an introduction to Monte Carlo (MC) methods, followed by an example of their usage in the case of quasielastic neutrino scattering off nucleon. The second part is devoted to the description of the models commonly used  in MC neutrino event generators. Finally, practical examples of running GENIE and NuWro are presented.

    12.2. Nuisance (2 hours)

    Mr. Patrick Stowell (Univ. Sheffield, UK)

    First we shall describe the experimental methods used to extract neutrino cross-sections and their limitations. The NUISANCE generator tuning framework will then be introduced through practical examples, comparing multiple generators to a single dataset, before using a simple likelihood fit to tune a free model parameter in one of the generators of choice. A virtual box containing the necessary software will be provided beforehand.

Travel

The school will be held at Fermilab. For instructions on how to reach Fermilab please see here.

Fermilab’s main entrance is located at the intersection of Kirk Road and Pine Street in Batavia, Illinois, about 45 miles west of Chicago. Delivery trucks need to use the entrance at Kirk Road and Wilson Street. There is no street number assigned to this entrance location. When using a GPS navigation unit, please enter the intersection as your destination. Signs posted at the intersection will point you to the Fermilab entrance.

From Chicago, travel west on the Eisenhower (I-290) to I-88 (80 cents). Exit I-88 at the Farnsworth exit, north or right (60 cents). Farnsworth becomes Kirk Road. Follow Kirk Road to Pine Street. Turn right at Pine Street, Fermilab’s main entrance.

From O’Hare Airport, take I-90 east toward Chicago. After just a couple of miles, take I-294 south, toward Indiana (80 cents). From I-294 take the exit to I-88, the east-west tollway, toward Aurora (80 cents). From I-88, take the Farnsworth exit (60 cents). Turn north onto Farnsworth. Farnsworth becomes Kirk Road. Follow Kirk Road to Pine Street. Turn right on Pine Street, the main entrance to Fermilab. Come to Wilson Hall, the high-rise building. You’ll see it sticking up off the prairie.

From Midway Airport: Take Cicero Avenue north to the Stevenson Expressway South (I-55) to I-355 North (toward northern suburbs). Take I-355 to the East-West tollway (I-88). Take I-88 West for approximately 10 miles to the Farnsworth North exit and turn right. Travel 2.9 miles to the Pine Street entrance to the Fermilab site.

Venue
