Machine learning CICY threefolds / Bull, Kieran ; He, Yang-Hui ; Jejjala, Vishnu ; Mishra, Challenger
The latest techniques from Neural Networks and Support Vector Machines (SVM) are used to investigate geometric properties of Complete Intersection Calabi–Yau (CICY) threefolds, a class of manifolds that facilitate string model building. [...]

SU (3) knot solitons: Hopfions in the F 2 Skyrme–Faddeev–Niemi model / Amari, Yuki ; Sawado, Nobuyuki
We discuss the existence of knot solitons (Hopfions) in a Skyrme–Faddeev–Niemi-type model on the target space SU(3)/U(1)2 , which can be viewed as an effective theory of both the SU(3) Yang–Mills theory and the SU(3) anti-ferromagnetic Heisenberg model. [...]

Dirac neutrino mixings from hidden μ – τ symmetry / Luna Terrazas, Edgar R. ; Pérez-Lorenzana, Abdel
We explore masses and mixings for Dirac neutrinos in models where lepton number is conserved, under the guidance of a hidden, but broken, μ – τ exchange symmetry, that makes itself evident in the squared hermitian mass matrix. [...]

On ( q , t )-deformation of Gaussian matrix model / Morozov, A. ; Popolitov, A. ; Shakirov, Sh.
The recently discovered general formulas for perturbative correlators in basic matrix models can be interpreted as the Schur-preservation property of Gaussian measures. [...]

Exploring scalar and vector bileptons at the LHC in a 331 model / Corcella, Gennaro ; Corianò, Claudio ; Costantini, Antonio ; Frampton, Paul H.
We present an analysis on the production of two same-sign lepton pairs at the LHC, mediated by bileptons in the SU(3)c×SU(3)L×U(1)X theory, the so-called 331 model. [...]

Minimal dark matter in SU (2) L  ×  U (1) Y  ×  U (1) B − L / Cai, Chengfeng ; Kang, Zhaofeng ; Zhang, Hong-Hao ; Zeng, Yupan
The minimal gauge group extension to the standard model (SM) by the local U(1)B−L (MBLSM) is well known as the minimal model to understand neutrino mass origins via the seesaw mechanism, following the gauge principle. [...]

The MESS of cosmological perturbations / Romano, Antonio Enea ; Vallejo Peña, Sergio A.
We introduce two new effective quantities for the study of comoving curvature perturbations ζ : the space dependent effective sound speed (SESS) and the momentum dependent effective sound speed (MESS). [...]
