The Payment Heterogeneity Index: An Integrated Unsupervised Framework for High-Volume Procurement Oversight and Decision Support
Kyriakos Christodoulides
Public procurement is vulnerable to error, fraud, and corruption, particularly as high transaction volumes overwhelm oversight. While research often focuses on tender-stage anomali…
Top Quark Mass in Exophobic Pati--Salam Heterotic String Model
Kyriakos Christodoulides, Alon E. Faraggi, John Rizos
We analyse the phenomenology of an exemplary exophobic Pati-Salam heterotic string vacuum, in which no exotic fractionally charged states exist in the massless string spectrum. Our…
Classification of Heterotic Pati-Salam Models
Benjamin Assel, Kyriakos Christodoulides, Alon E. Faraggi +2
We extend the classification of free fermionic heterotic-string models to vacua in which the SO(10) GUT symmetry is broken at the string level to the Pati-Salam subgroup. Using our…
Exophobic Quasi-Realistic Heterotic String Vacua
Benjamin Assel, Kyriakos Christodoulides, Alon E. Faraggi +2
We demonstrate the existence of heterotic-string vacua that are free of massless exotic fields. The need to break the non-Abelian GUT symmetries in k=1 heterotic-string models by W…
