Secluded U(1) below the weak scale [PDF]
, 2008 A secluded U(1) sector with weak admixture to photons, O(10{sup -2}-10{sup -3}), and the scale of the breaking below 1 GeV represents a natural yet poorly constrained extension of the standard model.

Cosmology from weak lensing peaks and minima with Subaru Hyper Suprime-Cam survey first-year data [PDF]
, 2023 We present cosmological constraints derived from peak counts, minimum counts, and the angular power spectrum of the Subaru Hyper Suprime-Cam first-year (HSC Y1) weak lensing shear catalog.

Contributions to the muon g − 2 from a three-form field
Journal of High Energy Physics, 2023 We examine contributions to the muon dipole moment g − 2 from a 3-form field Ω, which naturally arises from many fundamental theories, such as the string theory and the hyperunified field theory. In particular, by calculating the one-loop Feynman diagram,

Integrated approach to cosmology: Combining CMB, large-scale structure and weak lensing [PDF]
, 2016 Recent observational progress has led to the establishment of the standard $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ model for cosmology. This development is based on different cosmological probes that are usually combined through their likelihoods at ...

Probing electroweak phase transition in the singlet Standard Model via bbγγ and 4l channels
Journal of High Energy Physics, 2023 We investigate the prospects for resonant di-Higgs and heavy Higgs production searches at the 14 TeV HL-LHC in the combination of bbγγ and 4l channels, as a probe of a possible first order electroweak phase transition in real singlet scalar extension of ...

TASI Lectures on Flavor Physics [PDF]
, 2015 These notes overlap with lectures given at the TASI summer schools in 2014 and 2011, as well as at the European School of High Energy Physics in 2013. This is primarily an attempt at transcribing my hand-written notes, with emphasis on topics and ideas ...

Top Quark Compositeness: Feasibility and Implications [PDF]
, 2008 In models of electroweak symmetry breaking in which the SM fermions get their masses by mixing with composite states, it is natural to expect the top quark to show properties of compositeness.

Rare b hadron decays at the LHC
, 2015 With the completion of Run~I of the CERN Large Hadron Collider, particle physics has entered a new era. The production of unprecedented numbers of heavy-flavoured hadrons in high energy proton-proton collisions allows detailed studies of flavour-changing

Non-Gaussian information from weak lensing data via deep learning [PDF]
arXiv.org, 2018 Weak lensing maps contain information beyond two-point statistics on small scales. Much recent work has tried to extract this information through a range of different observables or via nonlinear transformations of the lensing field.

, 2010 Six major frameworks have emerged attempting to describe particle physics beyond the Standard Model. Despite their different theoretical genera, these frameworks have a number of common phenomenological features and problems.
