Clearly they have found something which appears to be the proposed boson and they will now need to confirm their findings and then investigate the properties of the boson, but where does the road lead after confirmation and dissection? What mysteries stand to be solved and how? ...

There are lots of puzzles in the Standard Model. Here are its free parameters:

Quark, lepton masses: 9

Quark mixing angles: 4

Strong CP-violation angle: 1

Gauge "charges": 3

Higgs-particle parameters: 2

Total: 19

Neutrino masses and mixing angles add another 3 + 4 = 7, for a grand total of 26.

Its gauge-multiplet structure is rather byzantine. Its overall gauge symmetry is SU(3)*SU(2)*U(1)

SU(3) -- Quantum Chromodynamics

SU(2) -- Weak Isospin

U(1) -- Weak Hypercharge: average electric charge of a weak-isospin multiplet

Electric charge: (weak-isospin projection) + hypercharge

QCD multiplets: 3: quark, 3*: antiquark, 8: gluon (quark * antiquark - colorless)

WIS multiplets: number is how many particles are in them

(QCD multiplet, WIS multiplet, WHC value)

Gauge:

gluon g (QCD carrier): (8,1,0)

W (WIS carrier): (1,3,0)

B (WHC carrier): (1,1,0)

Electroweak symmetry breaking: the W+ and W- become massive, while the W0 and B mix to make the photon (massless) and the Z (massive)

Higgs H: (1,2,1/2) or (1,2,-1/2)

Elementary fermions: 3 generations, both left-handed and right-handed. I'm listing antiparticles here also; they have reverse chirality / handedness.

Left-handed quark Q: (3,2,1/6) -- (3*,2,-1/6)

Right-handed up U: (3,1,2/3) -- (3*,1,-2/3)

Right-handed down D: (3,1,-1/3) -- (3*,1,1/3)

Left-handed lepton L: (1,2,-1/2) -- (1,2,1/2)

Right-handed neutrino N: (1,1,0) -- (1,1,0)

Right-handed electron E: (1,1,-1) -- (1,1,1)
