Paper #1 - due February 6:
Read the linked paper by the "CJ" collaboration and look at this sample plot of the collinear PDFs for Q2=1.7 GeV2. (You can also check out the CJ Website).
Summarize in your own words in 2-3 pages the main points of the CJ
analysis and the paper. In particular, address the following questions:
- What types of experiments
are used to extract the necessary information for the global fit? How
can the various PDFs for u,d,s quarks and antiquarks and for gluons be
separated from each other using these experiments?
- Why are the s-quark and the s-bar quark PDFs on top of each other?
- At what value of x can we say that the valence u and d quarks (i.e. the difference between quark and antiquark distribution) begin to dominate over all other PDFs?
- What would you expect to happen if I had created the same sample plot at much higher Q2? Just some qualitative differences you would expect to see.
- What are some of the specific features of this global fit in comparison to others on the market?
Paper #2 - due March 6 [Bring to my office, hand me in person or email to me ANYTIME before 5 p.m. on Friday, March 8!]:
Read the two papers on planned spectator tagging experiments: One ("BONuS12") at Jefferson Lab's CLAS12 using 12 GeV beam, and the other using the Electron Ion Collider (if
built at Jefferson Lab). Discuss the similarities and differences
between the two proposed measurements. In particular, address the
Note: the two papers use slightly different nomenclatures - to compare
them more directly, calculate the "initial mass squared" M*2
of the neutron before it is struck (according to BONuS12) with the
variable "t" introduced in the EIC paper. Express both in terms of the
spectator momentum ps. Don't hesitate to ask me if you questions! See also Spectator Tagging with JLEIC
- What are the reasons to use spectator tagging instead of simple DIS?
- How do the two experiments differ in terms of the quantities they aim to measure?
- How do the two experiments differ in terms of kinematic coverage?
do the methods employed differ? What are the technical advantages of
the EIC experiment (assuming that lower spectator momenta "are better")?
- Can you guess why the BONuS12 experiment cannot go all the way down to ZERO spectator momentum (in the deuteron rest frame)?
Paper #3 - due April 8Using material on this web page and in text books or on
the web, give two or three examples how nuclear/particle physics can
explain observations of phenomena in the universe or answer fundamental questions
about the origin of "everything". Describe concrete experiments or
theoretical calculations that can support this quest. 3 pages minimum.
Final Paper #4 - due May 6 (Final)
Pick ONE of the experiments discussed in the last quarter of the
semester, on fundamental symmetries, extensions of the Standard Model,
and neutrinos. Find out as much information about that experiment as
you can (go to web sites, search for publications in the literature,
check arXive and/or INSPIRE). Then write up a more detailed description
of the experiment, including the underlying theory (what does it
measure? How? What can we learn about Nature from it? Technique, time
plan, preconditions? Theory?)
4 pages minimum (you are allowed and even encouraged to add figures, graphs, photos etc.).
