The bearable compositeness of leptons

open access: yesJournal of High Energy Physics, 2018
Partial compositeness as a theory of flavor in the lepton sector is assessed. We begin presenting the first systematic analysis of neutrino mass generation in this context, and identifying the distinctive mass textures.

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

Strong dynamics with matter in multiple representations: $$\mathrm {SU}(4)$$ SU(4) gauge theory with fundamental and sextet fermions

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We present a non-perturbative lattice study of $$\mathrm {SU}(4)$$ SU(4) gauge theory with two flavors of fermions in the fundamental representation and two in the two-index antisymmetric representation: a theory closely related to a minimal partial ...

Anatomy of the newly observed hidden-charm pentaquark states: Pc(4312), Pc(4440) and Pc(4457)

open access: yesPhysics Letters B, 2019
We study the newly reported hidden-charm pentaquark candidates Pc(4312), Pc(4440) and Pc(4457) from the LHCb Collaboration, in the framework of the effective-range expansion and resonance compositeness relations.

Search for a heavy composite Majorana neutrino in events with dilepton signatures from proton-proton collisions at s=13 TeV

open access: yesPhysics Letters B, 2023
Results are presented of a search for a heavy Majorana neutrino Image 1 decaying into two same-flavor leptons ℓ (electrons or muons) and a quark-pair jet. A model is considered in which the Image 1 is an excited neutrino in a compositeness scenario.

Probing compositeness with the CMS eejj & eej data

open access: yesPhysics Letters B, 2016
Quark-lepton compositeness is a well-known beyond the Standard Model (SM) scenario with heavy exotic particles like leptoquarks (LQs) and leptogluons (LGs) etc. These particles can couple to leptons and jets simultaneously.

Addressing six standard model problems with Technically Natural Higgs models

open access: yesJournal of High Energy Physics, 2023
We aim to study the potential of the recently proposed model framework, called Technically Natural Higgs (TNH), in addressing six fundamental problems in particle physics and cosmology.

Bone Mineral Density After Contemporary Treatment for Acute Lymphoblastic Leukaemia: A Matched Cross‐Sectional Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Reduced bone mineral density (BMD) has been reported in survivors of childhood and young adult acute lymphoblastic leukaemia (ALL); however, data from cohorts treated with contemporary protocols and including matched controls remain limited.

Sigma-assisted low scale composite Goldstone–Higgs

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We show that the presence of a lightish scalar resonance, $$\sigma $$ σ , that mixes with the composite Goldstone–Higgs boson can relax the typical bounds found in this class of models.

Exercise Capacity, Physical Activity, Fatigue, and Neurocognitive Function in Adult Survivors of Childhood Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...
