v12 v13 14 14 The particle spectra of 2UED includes all of the Standard Model particles as well as their Kaluza-Klein excitations in either one or both of the compactified extra dimensions. Upon compactification one recovers the four dimensional gauge fields, but are left with 2 extra components. One of these components, the spinless adjoint to the gauge field, is invariant under 6D gauge transformations. The other, orthogonal excitation, shifts under such a transformation and corresponds to the Nambu-Goldstone boson eaten by the massive vector gauge field level by level. The 6D fermions have four components corresponding to the + or - 6D chiralities and the familiar L and R 4D chiralities. In order to insure 6D anomaly cancellation and fermion mass generation, the chiralities of the weak-doublet quarks (leptons) are forced to be opposite those of the weak-singlet quarks (leptons). That is, for each generation of quarks, there are the following fields: Q+ = (U+,D+), U-, D-, as well as the analogous fields for the leptons, including a - chirality neutrino field. Each of these 6D chiralities is composed of a combination of L and R handed components. Below is a table summarizing the 2UED particle content for the (0,0), (1,0) and (1,1) levels of excitation, where (0,0) are the standard model fields, (1,0) are fields with excitations in 1 extra dimension and (1,1) are fields with excitations in both extra dimensions. 15 15 16 ||''' ''Standard Model F ields'' '''||||||||||||16 ||''' ''Standard Model Fermion Fields'' '''|||||||||||| 17 17 ||'''Particle Name'''||'''Mode'''||'''Description'''||'''FeynRules Name'''||'''MG Name'''||'''CH Name'''|| 18 18 ||u||(0,0)||Standard Model up quark||u ||u|| || … … 28 28 ||tau||(0,0)||Standard Model tau ||tt||tt|| || 29 29 ||vtau||(0,0)||Standard Model tau neutrino||vt||vt || || 30 ||''' ''Standard Model Gauge Fields'' '''|||||||||||| 30 31 ||A||(0,0)||Standard Model photon ||A||a || || 31 32 ||Z||(0,0)||Standard Model Z-boson ||Z||z || || … … 33 34 ||g||(0,0)||Standard Model gluon ||G||g || || 34 35 35 ||''' '' (1,0)Fields'' '''||||||||||||36 ||''' ''KK (1,0) Fermion Fields'' '''|||||||||||| 36 37 ||'''Particle Name'''||'''Mode'''||'''Description'''||'''FeynRules Name'''||'''MG Name'''||'''CH Name'''|| 37 38 ||Uq10+||(1,0)||Chirality + up quark||u1p ||u1p|| || … … 59 60 ||Tau10-||(1,0)||Chirality - tau||tt1m||tt1m-|||| 60 61 ||VTau10-||(1,0)||Chirality - tau-neutrino||vt1m||vt1m-|||| 61 ||B10||(1,0)||Chirality + tau-neutrino||vt1m||vt1m-|||| 62 ||''' ''KK (1,0) Gauge Fields'' '''|||||||||||| 63 ||B10||(1,0)||Vector KK photon ||B10||B10|||| 64 ||BH10||(1,0)||Scalar KK photon||BH10||BH10|||| 65 ||W10||(1,0)||Vector KK W||W10||W10+|||| 66 ||WH10||(1,0)||Scalar KK W||WH10||WH10+|||| 67 ||Z10||(1,0)||Vector KK Z||Z10||Z10|||| 68 ||ZH10||(1,0)||Scalar KK Z||ZH10||ZH10|||| 69 ||G10||(1,0)||Vector KK Gluon||G10||G10|||| 70 ||GH10||(1,0)||Scalar KK Gluon||GH10||GH10|||| 71 62 72 63 73
