saving a new nested array having properties of dynamic dimension

[gsaha009]

Hello experts,

I have a main awkward record named events which has several fields like muon, tau, met etc. Now, I want to add a new field to the events array e.g. higssCand which looks like the following:

Say, I have three entries in the events array, and this higgsCand is basically a pair of muon and tau

higgsCand = [ [m,t], [m,t], [m,t] ]
# fields of higgsCand
pt : [ [45.5, 43.2], [34.3, 32.1], [87.1,54,2] ]
# more fields of the same dimension
# now is there any way to add something like the following
mT_comb: [ [41.2], [54.4], [74.6] ] # in this same higgsCand array?

So, if I call events.higgsCand.pt, it will return the pt array, and if I do events.higgsCand.mT_comb, it will return me the mT_comb array which has a different dimension than pt

Is it fundamentally possible at all?

Thank you very much :)

Do you mean something other than the following?

events["higgsCand"] = higgsCand

(See ak.Array.__setitem__.)
