2 | 8/16/2021 10:38:26 | 1 | 6 | Where do the different gauge symmetries SU(3)xSU(2)xU(1) come from and why do we require each of them? | answered live | |||||
3 | 8/16/2021 10:40:25 | 1 | 9 | Why does the scalar field minimize the potential? | answered live | |||||
4 | 8/16/2021 10:52:25 | 1 | 13 | Does this plot mean that there is no quartic coupling at high energies? What does a negative quartic coupling mean? | answered live | |||||
5 | 8/16/2021 10:52:52 | 1 | 14 | How sensitive is the stability condition to new physics? | answered live | |||||
6 | 8/16/2021 10:56:08 | 1 | How did we know the value of the Higgs vacuum expectation value v? | answered live | ||||||
7 | 8/16/2021 11:02:17 | 1 | 16 | What is the physical meaning of 6 degrees of freedom for the W+/W-? | answered live | |||||
8 | 8/16/2021 11:13:13 | 1 | Slide 7 | Could you explain again what “not stable wrt quantum corrections” means? Does this refer to the effect that such corrections have on the Higgs mass? | answered live | |||||
9 | 8/16/2021 11:27:28 | 1 | Why the Higgs needs to be spin 0? | answered live | ||||||
10 | 8/16/2021 11:31:22 | 1 | When talking about W+ and W-, does it have to be after EWSB? And, when talking about W123, does it have to be before EWSB? | answered live | ||||||
11 | 8/16/2021 11:35:31 | 1 | Since the gauge couplings do not lead us to neutrino mass, do you expect a second Higgs which will get us to the neutrinos | |||||||
12 | 8/17/2021 5:07:43 | 1 | 18 | You have mentioned the 4 input parameters for SM including the mass of the Higgs boson. But before the discovery of Higgs boson in 2012 we could calculate all observables in the SM including the one-loop EW corrections without knowledge of the mass of Higgs boson. | ||||||
13 | 8/17/2021 9:14:37 | 2 | 6 | why do heavy quarks decouple in the gluon fusion process? | answered live | |||||
14 | 8/17/2021 9:14:37 | 2 | slide 6 | What does it mean here that heavy quarks do not decouple? | ||||||
15 | 8/17/2021 9:28:32 | 2 | 12 | What is the difference between "SM" and "theory" in the subscripts? | answered live | |||||
16 | 8/17/2021 9:31:59 | 2 | 12 | What is the width of the higgs boson ? | ||||||
17 | 8/17/2021 9:32:39 | 2 | 13 | Can you please elaborate on the kappa_top here in the plot? | answered live | |||||
18 | 8/17/2021 9:41:28 | 2 | 16 | How to definition of the quark b and top mass? | answered live | |||||
19 | 8/17/2021 9:42:13 | 2 | 16 | How is Kappa and mu parameter different? Aren't they both ( experimental value / SM value ) ? | answered live | |||||
20 | 8/17/2021 9:48:24 | 2 | 18 | What is the mu in this page? Is it a scale or is it the kappa for muon Yukawa? | answered live | |||||
21 | 8/17/2021 9:50:58 | 2 | 17 | For the H> J/psi+gamma decay, how well can we determin J/psi at LHC? And, that process is dominated by the gamm/Z channel, is this a big problem in determining charm Yukawa? | answered live | |||||
22 | 8/17/2021 10:00:31 | 2 | 13 | Since the coupling to quarks (i.e top) is part of the production of the Higgs boson, this would mean that this coupling is measured in several measurements that focuses on other decay processes of the Higgs. Shouldn't this coupling therefore be one of the best measured ones? Why is that not the case? | answered live | |||||
23 | 8/17/2021 10:01:20 | 1 | Although the electron-higgs' electron coupling is small, can't we rely on loop level couplings through an intermediate field that could be significant? | |||||||
24 | 8/17/2021 10:02:46 | 2 | 13 | Are there negative kappas for the other particles. Why single out the top ? | answered live | |||||
25 | 8/17/2021 10:09:22 | 2 | Since Kappa is (theory / SM) isn't it model dependent? When one mentions a kappa value should the model be specified? | |||||||
