Abstract
In this article, we show that making global fits of string theory model parameters to data is an interesting mechanism for probing, mapping and forecasting connections of the theory to real world physics. We considered a large volume scenario (LVS) with D3-brane matter fields and supersymmetry breaking. A global fit of the parameters to low-energy data shows that the set of LVS models are associated with light gluinos which are quasi-degenerate with the neutralinos and charginos they can promptly decay into, and thus they are possibly hidden to current LHC gluino search strategies.

Summary
Flux compactification with stabilised moduli sets a connection of string theory models to real world physics [1,2]. Sampling string theory-based model parameters for making global fits to certain experimental data, representing the real world, could be the best way for finding explicit models in agreement with observations. Non-agreement between the predicted observables and their corresponding experimentally measured values or limits can be used for marking the point W0 as not suitable for representing our world This way, statistical methods for exploration and fitting the landscape parameters can be used for mapping and physics forecasting. The set of LVS parameters, { x, α1, y, ωs, tan β, log m3/2}, in the soft supersymmetry-breaking terms above together the RG to the weak scale with MSSM sparticle content is referred to as the LVS MSSM with six parameters (LMSSM-6). We describe the procedure for fitting the parameters to low-energy data
