Dear Tom,
it would be great if the talks could be listed as two separate 10 minute
talks in the agenda. If that is not possible, here is a title + abstract
for the combined talk:
Constraining the nuclear gluon and strange PDFs with heavy quark
production and neutrino scattering
Nuclear parton distribution functions (nPDFs) of gluons and strange
quarks have been the subject of many studies over the past years, since
they are important for many processes and difficult to constrain. Two
new analyses in the nCTEQ framework are presented to address these
issues. The first takes a new look at neutrino DIS data which was
previously excluded due to tensions with charged-lepton DIS and finds a
subset of data that can safely be used to constrain the strange quark.
The second analysis introduces heavy quark production data into the
global fit using a data driven approach to constrain the gluon at
x-values down to 10^-5.
Thanks,
Pit

Dear Pit, Khoirul, Karol, Michael, Fred,
Thank you for your quick response to our request and for your
understanding. Both of your abstracts are of course of significant
interest to our working group and we recognise that their focus is
somewhat different, albeit both within nCTEQ. Unfortunately as it
stands, we are currently are only able to accept one nCTEQ talk (in
the unlikely event this were to change, e.g. due to some
cancellations, we can let you know), furthermore all talks are
currently envisaged 20 minutes long. Therefore we would propose that
we assign you one talk slot of 20 minutes and then how you wish to
divide it between the two talks you can decide, e.g. perhaps you
prefer two back-to-back 10 minute talks to cover the two abstracts,
please let us know if this would work for you?
Thanks again for your understanding.
Tom (for WG1 conveners - Tom, Barak, Klaus)

Dear Tom, Barak, Klaus,
Thanks for your note, and we are pleased to hear of the considerable
interest in this year's DIS workshop.
We briefly discussed the possibility of merging the "Heavy Quark" and
"Neutrino" talks, but concluded this would be difficult as the topics
are, in fact, quite separate and focus on very different data sets.
We've attached the cover pages of the current drafts (both papers will
be on the ArXiV before the meeting) to highlight the contrasting
objective of each.
The heavy quark study is led by Pit Duwentaester and Michael Klasen,
and is looking at the heavy quark meson data from RHIC and LHC. This
analysis provides new constraints on the gluon PDF in the small-x
region. The output of this study is a new nCTEQ15HQ PDF set.
In contrast, the neutrino study (led by Khoirul Faiq Muzakkaand and
Karol Kovarik) uses the results of the new nCTEQ15WZSIH PDFs, along
with three independent compatibility criteria to definitively address
the observed tensions between the DIS charged current and neutral
current processes. The output of this study is a new nCTEQ15nu PDF set.
We certainly appreciate the limited time available for your working
group. Therefore, if it might be possible to have two separate shorter
talks, that would be much preferable for us. We could coordinate to
eliminate any overlapping introductory material, thus enabling the
speakers to adequately cover the core elements.
Thank you for your consideration,
Pit Duwentäster, Khoirul Faiq Muzakka, Karol Kovarik, Michael Klasen,
Fred Olness
