Hierarchies from landscape probability gradients and critical boundaries
If the gradient of a probability distribution on a landscape of vacua aligns with the variation of some fundamental parameter, the parameter may be likely to take some non-generic value.

Multiple point criticality principle and Coleman-Weinberg inflation
We apply the multiple point criticality principle to inflationary model building and study Coleman-Weinberg inflation when the scalar potential is quadratic in the logarithmic correction.

Cosmological Constraints on Interacting Light Particles
Cosmological observations are becoming increasingly sensitive to the effects of light particles in the form of dark radiation (DR) at the time of recombination.

Geographic distribution of shared mtDNA haplotypes between. This map shows the geographic distribution of shared mtDNA haplotypes between the human remains of Puyil Cave and those reported previously from ancient and contemporary people. Additionally, in the bottom right corner are shown the skulls on the surface of Chamber 4, discovered in this cave ...

Beyond Standard Model Searches in the MiniBooNE Experiment
The MiniBooNE experiment has contributed substantially to beyond standard model searches in the neutrino sector. The experiment was originally designed to test the Δm2 ~ 1 eV2 region of the sterile neutrino hypothesis by observing νe(ν-e) charged current quasielastic signals from a νμ(ν-μ) beam.

Thermal production of astrophobic axions
Hot axions are produced in the early Universe via their interactions with Standard Model particles, contributing to dark radiation commonly parameterized as ∆N eff.

BBN photodisintegration constraints on gravitationally produced vector bosons
Gravitational production of massive particles due to cosmic expansion can be significant during the inflationary and reheating period of the Universe. If the particle also has non-gravitational interactions that do not significantly affect its production,

Phenomenological Hints from a Class of String Motivated Model Constructions
We use string theory constructions towards the generalisation of the supersymmetric standard model of strong and electroweak interactions. Properties of the models depend crucially on the location of fields in extradimensional compact space. This allows us to extract some generic lessons for the phenomenological properties of the low energy effective ...

A novel probe of supersymmetry in light of nanohertz gravitational waves
A new era of exploring the early Universe may have begun with the recent strong evidence for the stochastic gravitational wave (GW) background from the data reported by NANOGrav, EPTA (including InPTA data), PPTA, and CPTA. Inspired by this, we propose a
