A radiative neutrino mass model with leptoquarks under non-holomorphic modular A 4 symmetry

Journal of High Energy Physics
We investigate a radiative seesaw model with two leptoquarks under non-holomorphic modular A 4 symmetry. The leptons and quarks belong to non-trivial representations of the modular A 4 and the structures of their mass matrices are restricted.

Probing new physics with charge asymmetries in 2 same-sign leptons plus jets final states at the LHC

Journal of High Energy Physics
We study the impact of new physics models in the charge asymmetry defined for LHC final states consisting of two same-sign leptons (2SSl, with l = e, μ) plus jets (N jets ≥ 2), with a center-of-mass energy of s $$ \sqrt{s} $$ = 13 TeV, where the main SM ...

Statistical methods in weak gravitational lensing [PDF]

, 2015
This thesis studies several topics in the area of weak gravitational lensing and addresses some key statistical problems within this subject. A large part of the thesis concerns the measurement of galaxy shapes for weak gravitational lensing and the ...

Weak Scale Effects in Growth Models [PDF]

, 2005
Growth models of the second generation type, e.g. the Jones (1995) or Young (1998) model, all exhibit a so called weak scale effect in per capita production, i.e. larger economies should have a higher per capita production than smaller economies. However,

Meson mixing bounds on Z ′ mass in the alignment limit: establishing the phenomenological viability of the 331 model

Journal of High Energy Physics
We perform a systematic study of flavor-changing neutral currents (FCNCs) in the 331 model with right-handed neutrinos (331RHNs), analyzing constraints on the Z ′ boson mass from K-, D-, B d -, and B s -meson oscillations.

Undecay

Journal of High Energy Physics
Unstable particles decay sooner or later, so they are not described by asymptotic one-particle states and they should not be included as independent states in unitarity relations such as the optical theorem.

Weak convergence of the sequential empirical processes of residuals in ARMA models [PDF]

This paper studies the weak convergence of the sequential empirical process $\hat{K}_n$ of the estimated residuals in ARMA(p,q) models when the errors are independent and identically distributed.

In search of an invisible Z′

Journal of High Energy Physics
We consider extending the Standard Model by an anomaly-free and possibly flavour non-universal U(1) X gauge symmetry, whose breaking gives a Z′ boson that does not affect electroweak precision observables at tree-level or via 1-loop renormalisation group

Two-loop corrections to the Higgs trilinear coupling in classically scale-invariant BSM models

, 2021
The Higgs trilinear coupling provides can serve as a unique probe to investigate the structure of the Higgs sector and the nature of the electroweak phase transition, and to search for indirect signs of New Physics. Meanwhile, classical scale invariance (

Barr-Zee diagrams at a high-energy muon collider

Journal of High Energy Physics
The sensitivity of electron EDM experiments has been increasing at a rapid pace, and could yield indications of new physics in the coming decade. An intriguing possibility is that an EDM signal could be generated by new, electroweak-charged particles at ...
