One String to Rule Them All: Neutrino Masses and Mixing Angles
Jordan Gemmill, Evan Howington, Van E. Mayes
The correct quark and charged lepton mass matrices along with a nearly correct CKM matrix may be naturally accommodated in a Pati-Salam model constructed from intersecting D6 brane…
All Fermion Masses and Mixings in an Intersecting D-brane World
Van E. Mayes
It is shown that neutrino mixing angles which are consistent with current experimental observations may be naturally obtained in a Pati-Salam model constructed from intersecting D6…
The GeV Diphoton Excesses in a Realistic D-brane Model
Tianjun Li, James A. Maxin, Van E. Mayes +1
We study the diphoton excesses near GeV recently reported by the ATLAS and CMS collaborations within the context of a phenomenologically interesting intersecting/magnetized D…
A Flippon Related Singlet at the LHC II
Tianjun Li, James A. Maxin, Van E. Mayes +1
We consider the 750 GeV diphoton resonance at the 13 TeV LHC in the - model with a Standard Model (SM) singlet field which couples to TeV-scale vector-like particl…
The Diboson Excesses in Leptophobic Models from String Theories
Tianjun Li, James A. Maxin, Van E. Mayes +1
The ATLAS Collaboration has reported excesses in the search for resonant diboson production with decay modes to hadronic final states at a diboson invariant mass around 2 TeV in bo…
Light Higgsino Dark Matter in the MSSM on D-branes
Van E. Mayes, Andrew W. Lutz
When supersymmetry breaking is dominated by the complex structure moduli and the universal dilaton, a subset of the supersymmetry parameter space in a realistic MSSM constructed fr…
Universal Soft Terms in the MSSM on D-branes
Van E. Mayes
In Type II string vacua constructed from intersecting/magnetized D-branes, the supersymmetry-breaking soft terms are genericaly non-universal. It is shown that universal supersymme…
SUSY into Darkness: Heavy Scalars in the CMSSM
Van E. Mayes
A survey of the mSUGRA/CMSSM parameter space is presented. The viable regions of the parameter space which satisfy all experimental constraints are identified and discussed. These…
Proton Stability and Dark Matter in a Realistic String MSSM
James A. Maxin, Van E. Mayes, D. V. Nanopoulos
We demonstrate the existence of an extra nonanomalous U(1) gauge symmetry in a three-generation Pati-Salam model constructed with intersecting D6-branes in Type IIA string theory o…
Gauged Baryon and Lepton Number in MSSM_4 Brane Worlds
Richard F. Lebed, Van E. Mayes
A recent D-brane model designed to accommodate a phenomenologically acceptable fourth generation of chiral fermions was noted to produce an unexpected additional unbroken nonanomal…
Natural Four-Generation Mass Textures in MSSM Brane Worlds
Richard F. Lebed, Van E. Mayes
A fourth generation of Standard Model (SM) fermions is usually considered unlikely due to constraints from direct searches, electroweak precision measurements, and perturbative uni…
Realistic Four-Generation MSSM in Type II String Theory
A. V. Belitsky, Richard F. Lebed, Van E. Mayes
We construct a four-generation MSSM with rank-4 Yukawa matrices from intersecting D6 branes on a T^6/(Z_2 x Z_2) orientifold. The Yukawa matrices obtained provide an example of Fla…
Stringy Neutralino Dark Matter in Light of CDMSII
James A. Maxin, Van E. Mayes, D. V. Nanopoulos
Recently, the CDMS experiment has reported the possible first direct-detection of dark matter. We update the direct-detection constraints for neutralino dark matter arising in a re…
A Note on Modulus-dominated SUSY-breaking
James A. Maxin, Van E. Mayes, D. V. Nanopoulos
In models where supersymmetry-breaking is dominated by the Kahler moduli and/or the universal dilaton, the B-parameter at the unification scale should be consistent with the value…
The Search for a Realistic String Model at LHC
James A. Maxin, Van E. Mayes, D. V. Nanopoulos
We survey the low-energy supersymmetry phenomenology of a three-family Pati-Salam model constructed from intersecting D6-branes in Type IIA string theory on the T^6/(Z_2 x Z_2) ori…
Stringy WIMP Detection and Annihilation
James A. Maxin, Van E. Mayes, Dimitri V. Nanopoulos
We calculate the direct dark matter detection spin-independent and proton spin-dependent cross-sections for a semi-realistic intersecting D6-brane model. The cross-sections are com…
Supergravity and Superstring Signatures of the One-Parameter Model at LHC
James A. Maxin, Van E. Mayes, Dimitri V. Nanopoulos
Many string constructions have a classical no-scale structure, resulting in a one-parameter model (OPM) for the supersymmetry breaking soft terms. As a highly constrained subset of…
Realistic Yukawa Textures and SUSY Spectra from Intersecting Branes
Ching-Ming Chen, Tianjun Li, V. E. Mayes +1
We study the possible phenomenology of a three-family Pati-Salam model constructed from intersecting D6-branes in Type IIA string theory on the T^6/(Z2 x Z2) orientifold with some…
Flipped Cryptons and the UHECRs
John Ellis, V. E. Mayes, D. V. Nanopoulos
Cryptons are metastable bound states of fractionally-charged particles that arise generically in the hidden sectors of models derived from heterotic string. We study their properti…
