2
8/24/2021 9:19:211You mentioned "integrating out". I have heard other lecturers use this term as well. Can you explain what that means?
3
8/24/2021 9:23:151GeneralUnder what conditions does EFT fail to describe new physics? When should we not trust it?
4
8/24/2021 9:26:211?Can EFT describe new resonant phenomena?
5
8/24/2021 9:27:521EPS slide 2Why is the y- variable different for fermions and vectors?
6
8/24/2021 9:34:191?For any given process of interest, how do we know when to truncate the EFT expansion?
7
8/24/2021 9:47:081If EFT Lagrangian is not renormalizable then how we will obtain finite numbers for observable's computed using this Lagrangian?
8
8/24/2021 9:50:311Simple example EFTWhat is "p" in the expansion of (p/m_S)^2, (p/m_s)^4 etc?
9
8/24/2021 9:55:021Last slideHow does Delta^4 bring down two powers of p to give a term ~ p^2/m_S ^2 term?
10
8/24/2021 9:59:141What would happen if the EFT doesn't realize the SM symmetries linearly?
11
8/25/2021 9:05:322
Dimension 5, 6, etc operators
What dimensions are we talking about? And how do we count? For example, you showed that dimension six is (h^2 del^2 h^2) / Lambda^2...
12
8/25/2021 9:10:282First pageFrom the example of the singlet yesterday, I understand that different BSM models will lead to different effective operators. How do we account for all of them in a systematic way?
13
8/25/2021 9:10:3221Do dim-6 or higher EFT operators renormalize the Higgs mass relationship given by the SM?
14
8/25/2021 9:12:5321How do you renormalize a theory containing non-renormalizable operators from an EFT?
15
8/25/2021 9:52:522Global EFT fitsWhat information do you need from the experimentalists to reinterpret an already published analysis in the context of SMEFT? Do you need the actual data points in all analysis bins?
16
8/25/2021 9:56:162What would an excess look like when looking at the SMEFT fit results? Which plots would show the excess?
17
8/25/2021 9:56:402Global EFT fitsHow sensitive are the EFT fits to a particular UV model when compared to a limit extracted specifically for that model?
18
8/25/2021 9:57:162
Theoretical framework
In the 4th choice, the determination of these parameters is also subject to some NP contamination, is this effect taken into account in these global analyses?
19
8/25/2021 9:59:312If an operator has a limit at 10 TeV, does that mean that new physics in interactions involving that operator is unlikely to show up until we reach higher energy scales?
20
8/25/2021 10:10:112If we just consider a few number of observables which are affected by a few number of operators, we make a mistake or we lose information?
