Sounds good. Could you add that to the slides? I can then officially approve it. Thanks.

Best

So to accommodate "plausible", shall we add a question mark to the end of the sentence?

Hi Raghav,

 

Sounds plausible. However, I think one should definitely follow this up after HP.

Thanks

Hi Joern, 

 

I sent this yesterday but it probably got lost in the other emails - 

 

for monika’s mu observable - i think i have an example of a punchy physics statement after brainstorming with Helen offline - 

 

so we know that mass is connected to virtuality yes. mu is mass fraction of the leading daughter compared to the mother. so it is essentially studying the rate of ‘virtuality reduction’ in our jet. Monika’s data shows mu having a slight dependence on rg. while the distributions don’t move as dramatically as the kT or change shape as the zg, we can see that the mean moves to the left as we reduce the rg values. 

 

so here is my statement - the <mu> going to smaller values with smaller rg is evidence of virtuality reduction in our jets. smaller values of mu imply a fast reduction of the virtuality. on the contrary, mu being large means that the leading daughter carries more of the virtuality or mass from the mother which only happens at large angles. 

 

for the plenary talk - “Shift of \mu to smaller values at smaller angles indicates a faster reduction of virtuality in the jet shower”. 

 

thoughts? 

 

Cheers
Raghav

Hi Helen, Raghav et al,

 

If there is consensus on a formulation for the groomed mass fraction on p8 (latest version), please let us know and we can update accordingly.

 

Thanks

Hello Helen,

Thank you for your comments.
