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 ...

Minimal Fundamental Partial Compositeness [PDF]

open access: yes, 2017
Building upon the fundamental partial compositeness framework, we provide consistent and potentially complete composite extensions of the Standard Model.

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.

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.

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.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

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.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

A more natural composite Higgs model

open access: yesJournal of High Energy Physics, 2020
Composite Higgs models provide an attractive solution to the hierarchy problem. However, many realistic models suffer from tuning problems in the Higgs potential. There are often large contributions from the UV dynamics of the composite resonances to the
