Hi Youqi,

It sounds reasonable. Please mention also in that slide what is "mistagged jet" in your case?

With this implemented, I sign off.

Cheers

Hi Nihar,

How about we use the term "mistagged jet"? i.e., we mistag the jet (at
detector level) as having two leading charged particles, but at truth
level one of the leading/subleading particles is neutral.

Best,
Youqi

Hi Youqi,

I fine with your reply except following.

Slide16: "this is a fake jet" -> "fake jet" is not a correct
phrase
this
context. You could use something else like "unused jets" . These
are
true jet but you are not using in your r_c observable.

I still think this jet should be considered "fake" for the purpose
of
this analysis. The jet shouldn’t be included for rc analysis
since
at truth level, one of its leading dihadrons is a neutral
particle.
However, we won't be able to know that from data, so it ends up
being
incorrectly included for the analysis. I have added a sentence to
explain this on the slide as well.

I disagree, the argument is:
This is not a "fake" jet. you are discarding it in your calculation
that
doesn't mean you should call it "fake" jet. They are "real jet" with

high pT. The "r_c" observable may not be reconstructed for this case

when you have a leading/subleading neutral constituent.

If we don't correct this nomenclature, it would create unnecessary
confusion in your analysis for future discussion and would be a
misleading. So I advise to adopt better wording.

Thank you
Nihar

Hi Nihar,

Thanks for the comments. I have implemented them and uploaded a
new
version on drupal.

Slide4: "... and in a" -> Not sure if it has any meaning.

Here I am trying to emphasize that the two measurements shown on
this
slide are multi-differential measurements, as opposed to the
inclusive
measurements shown on slide 3.

Hello Youqi,

Thank your for your nice slides on jet substructure measurement.

Please find my comment below.

Slide4: "... and in a" -> Not sure if it has any meaning.
References are too small to see. For example "STAR. DIS 2021"

Make "CollinearDrop" consistent everywhere, Some places you write
"collinear drop". Please check this out.

Slide14:
"Jets with a more DGLAP-like splitting are more likely to have
small

early-stage radiation" -> where did you discuss about "DGLAP"? I
could
not find.

Slide16: "this is a fake jet" -> "fake jet" is not a correct
phrase
this
context. You could use something else like "unused jets" . These
are

true jet but you are not using in your r_c observable.

Slide17:
"..have a unique sensitivity for non-perturbative effects" ->
Trying to
understand what exactly you want to say here.
This slide you may end up with some open questions or a bit
generic.
Up
to you.

Cheers
Nihar

Hi Youqi,

It looks like you addressed my comments from today’s
institutional
practice, so I only have a few remaining ones. With these
implemented, I sign off.

Enjoy Berkeley!

5. If you plan to say it verbally, then no need to add it as
text,
but it should be explained that a trivial weaker zcut is
justified
because the UE contribution to jets in pp is small.

9. I still think "MultiFold result" and "RooUnfold result" are
strange constructions. These are physics results, not results
on
the
correction method. So “RooUnfolded/MultiFolded result”
would
be
fine, similar to what you have at the bottom of the slide.

15. If you don’t get the Herwig before the talk, don’t
forget
to
remove it from the plot.

16. “fluctuation”; “neutral energy measurement for jet
p_T
below 20 GeV”; This “(smaller effect)” is also probably a
distraction from the discussion you want to have and could be
removed. I’ll leave it up to you.
