“…In both cases, these U(1) gauge bosons get Stückelberg masses. Since in these D-brane models M s is assumed to be O(TeV), the presence of these generic U(1)'s may be amenable to experimental tests at the LHC [34][35][36].…”

LHC phenomenology and cosmology of string-inspired intersecting D-brane models

We discuss the phenomenology and cosmology of a Standard-like Model inspired by string theory, in which the gauge fields are localized on D-branes wrapping certain compact cycles on an underlying geometry, whose intersection can give rise to chiral fermions. The energy scale associated with string physics is assumed to be near the Planck mass. To develop our program in the simplest way, we work within the construct of a minimal model with gauge-extended sectorThe resulting U (1) content gauges the baryon number B, the lepton number L, and a third additional abelian charge I R which acts as the third isospin component of an SU (2) R . All mixing angles and gauge couplings are fixed by rotation of the U (1) gauge fields to a basis diagonal in hypercharge Y and in an anomaly free linear combination of I R and B − L. The anomalous Z ′ gauge boson obtains a string scale Stückelberg mass via a 4D version of the Green-Schwarz mechanism. To keep the realization of the Higgs mechanism minimal, we add an extra SU (2) singlet complex scalar, which acquires a VEV and gives a TeV-scale mass to the non-anomalous gauge boson Z ′′ . The model is fully predictive and can be confronted with dijet and dilepton data from LHC8 and, eventually, LHC14. We show that M Z ′′ ≈ 3 − 4 TeV saturates current limits from the CMS and ATLAS collaborations. We also show that for M Z ′′ 5 TeV, LHC14 will reach discovery sensitivity 5σ. After that, we demostrate in all generality that Z ′′ milli-weak interactions could play an important role in observational cosmology. Finally, we examine some phenomenological aspects of the supersymmetric extension of the D-brane construct. * On leave of absence from CPHT Ecole Polytechnique, F-91128, Palaiseau Cedex.

“…This is of order g o M s . In this case, the Z does not generate Flavor Changing Neutral Currents (FCNC's) and it does not mix much with the Z, so minimal precision constraints are met and one can bound the mass of the Z in this model with collider data, as well as using bounds on the ρ parameter [86]. In this model it turns out that the Z is leptophobic and couples to quarks with a coupling constant related to the strong interactions.…”

This article discusses the status of string physics where the string tension is around the TeV scale. The article covers model building basics for perturbative strings, based on D-brane configurations. The effective low energy physics description of such string constructions is analyzed: how anomaly cancellation is implemented, how fast proton decay is avoided and how D-brane models lead to additional Z particles. This review also discusses direct search bounds for strings at the TeV scale, as well as theoretical issues with model building related to flavor physics and axions.
