Loop-generated neutrino masses in composite Higgs models

open access: yesJournal of High Energy Physics, 2021
We present a composite scotogenic model for neutrino masses, which are generated via loops of ℤ2-odd composite scalars. We consider three different approaches to the couplings of the neutrinos (including three right-handed singlets) and the composite ...

Inflation from the finite scale gauged Nambu–Jona-Lasinio model

open access: yesNuclear Physics B, 2017
The possibility to construct an inflationary universe scenario for the finite-scale gauged Nambu–Jona-Lasinio model is investigated. This model can be described by the Higgs–Yukawa type interaction model with the corresponding compositeness scale ...

Search for excited leptons in ℓℓγ final states in proton-proton collisions at s = 13 $$ \sqrt{\mathrm{s}}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2019
A search is presented for excited electrons and muons in ℓℓγ final states at the LHC. The search is based on a data sample corresponding to an integrated luminosity of 35.9 fb−1 of proton-proton collisions at a center-of-mass energy of 13 TeV, collected ...

Proton decay from quark and lepton compositeness

open access: yesJournal of High Energy Physics, 2022
Within a chiral SU(15) gauge theory in which the Standard Model fermions are bound states of massless preons, we show that proton-decay operators are likely induced at the compositeness scale, Λpre.

g μ − 2 from Vector-like leptons in warped space

open access: yesJournal of High Energy Physics, 2017
The experimental value of the anomalous magnetic moment of the muon, as well as the LHCb anomalies, point towards new physics coupled non-universally to muons and electrons.

Neutrino masses from low scale partial compositeness

open access: yesJournal of High Energy Physics, 2021
We consider a class of models in which the neutrinos acquire Majorana masses through mixing with singlet neutrinos that emerge as composite states of a strongly coupled hidden sector.

Anarchy with linear and bilinear interactions

open access: yesJournal of High Energy Physics, 2017
Composite Higgs models with anarchic partial compositeness require a scale of new physics O 10 − 100 $$ \mathcal{O}\left(10-100\right) $$ TeV, with the bounds being dominated by the dipole moments and ϵ K .

Integer factoring and compositeness witnesses

open access: yesJournal of Mathematical Cryptology, 2020
We describe a reduction of the problem of factorization of integers n ≤ x in polynomial-time (log x)M+O(1) to computing Euler’s totient function, with exceptions of at most xO(1/M) composite integers that cannot be factored at all, and at most x exp −cM ...

Anatomy of b → c τ ν anomalies

open access: yesJournal of High Energy Physics, 2018
In recent times, one of the strongest hints of Physics Beyond the Standard Model (BSM) has been the anomaly in the ratios R D and R D * $$ {R}_{D^{*}} $$ measured in the charged current decays of B-mesons.

Resolving muon g-2 anomaly with partial compositeness

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We consider the scenario of composite Higgs with partial compositeness to address the muon g-2 anomaly. We show that this anomaly is resolved by one-loop correction due to composite muon partners with mass scale of order TeVs and large Yukawa coupling to
