Family Gauge Bosons with an Inverted Mass Hierarchy Yoshio Koide (Osaka University) in collaboration with Toshifumi Yamashita (Maskawa Insititute, KSU) GUT2012, March 15, Kyoto U This workshop is on the Grand Unification Theory. Sorry, this talk is not a topic based on GUT. However, I think that a topic of family symmetries may give a suggestive hint on the flavor problem in GUT Based on ArXiv:

Contents 1. Motive to consider the inverted mass hierarchy* Brief review of the Sumino’s cancellation mechanism 2. Outline of the model (The details will be skipped.) 3. How different from the Sumino model? 4. How to observe the gauge boson effects (Note that the lowest gauge boson is.) 5. Summary * A family gauge bosons with the inverted mass hierarchy has been proposed by Grinstein et al. (2010) based on the triple SU(3) model. However, the phenomenology is quite different from ours because of the current structures.

1. Motive to consider the inverted mass hierarchy 1.1 Sumino’s motive to consider a family gauge symmetry 2009: Sumino has seriously taken why the mass formula is so remarkably satisfied with the pole masses: while if we take the running masses, the ratio becomes Under, K is invariant if. The deviation comes from the QED radiative correction

e e g -g In order to work the Sumino mechanism correctly , the following conditions are essential: (i) of the U(3) family symmetry (ii) Masses of the gauge bosons : Note that the contribution of (b) is zero in a SUSY model: Therefore, the Sumino mechanism cannot apply to a SUSY model. Therefore, Sumino has proposed an idea that the term is cancelled by a contribution from family gauge bosons (2009)

1.2 Our motive We would like to consider a Sumino-like mechanism which can work in a SUSY model. We propose a Sumino-like mechanism for the diagram (a). photon family gauge bosons In order that the cancellation works correctly, since  > 0, we consider differently from the Sumino’s gauge boson mass relation (Wave function renormalization diagram)

2. Outline of t he model By introducing two types of scalars and we build our model as follows: (i) The charged lepton mass matrix M e is given by (ii) Family gauge boson masses M ij are dominantly given by the VEV Therefore, we must show (iii) Gauge bosons take an inverted mass hierarchy: We must show For more details, see YK and TY, arXiv:

(i) Charged lepton mass matrix We assume the superpotential and we obtain where No time! Skip this page!

(ii) Relation We assume the superpotential We assume that is invariant under the exchange. Then, we obtain We take a diagonal form of Z as follows with z 1 2 +z 2 2 +z 3 2 =1 z 1 = , z 2 = , z 3 = No time! Skip this page!

(iii) Relation We assume the superpotential by introducing a field S Here, S is a family singlet field, and U(1) is softly broken by We can conclude that Thus, by neglecting the contribution of, we obtain No time! Skip this page!

3. How different from the Sumino model? Sumino K-Y Non-SUSY SUSY U(3) assignment of (e L, e R ) ~ (3,3*) ~ (3,3) Anomaly a model with anomaly an anomaly-less model Gauge boson Normal Inverted masses Family currents Effective appear not appear  N F =2 int. even if U q =1 in the limit of U q =1

4. How to observe the gauge boson effects Note that the family number is defined on the diagonal basis of the charged lepton mass matrix M e. Hadronic modes are in general dependent on the quark mixing matrices U u and U d. We know the observed values of but we do not know values of U u and U d individually. In the present model, we do not give an explicit model for quark mixings on the diagonal basis of M e. A constraint from mixing is highly dependent on a model of U d. We will not discuss it in this talk. The gauge boson model with the inverted mass hierarchy will bring a new view in the low energy (below TeV scale) phenomenology.

4.1 Deviation from the e-  universality in the tau decays We have family current-current interactions (z 1,z 2,z 3 ) = ( , , ) in addition to the conventional weak interactions We predict a deviation from the e-  universality The pure-leptonic decays are independent of a model of the quark mixing

Present experimental values lead to This result is in favor of the inverted gauge boson mass hierarchy. (For a normal mass hierarchy, R  will show R  < 1.) suggests i.e. This value seems to be somewhat low. We speculate ( a few TeV) The value will be confirmed by a tau factory in the near future.

4.2 Family number conserved semileptonic decays of ps-mesons Branching ratios of family number conserved semileptonic decays are not sensitive to explicit values of the quark mixings U u and U d. We predict those in the limit of U u =1 and U d =1 Observations of the K- and B-decays will be within our reach.

we speculate 4.3 Direct searches at LHC and ILC for the lightest gauge boson with a mass of a few TeV The searches are similar to Z’ searches, but we see only peak in  +  - channel (no peaks in e + e - and  +  - channels)

5. Summary The Sumino mechanism does not work for a SUSY model. In order to work a Sumino-like mechanism for a SUSY model, we must consider a family gauge boson model with an inverted mass hierarchy. Whether the gauge boson masses are inverted or normal is confirmed by observing the deviation form the e-  universality in the pure leptonic tau decays, i.e. or. The present observed values show which is in favor of the inverted mass hierarchy. Since we speculate that the lightest gauge boson mass is a few TeV, we expect the deviation A tau factory in the near future will confirm this deviation. We also expect a direct observation of  +  - in the LHC and the ILC.
