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.

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.

Top Compositeness at the Tevatron and LHC

open access: yes, 2007
We explore the possibility that the right-handed top quark is composite. We examine the consequences that compositeness would have on $t \bar{t}$ production at the Tevatron, and derive a weak constraint on the scale of compositeness of order a few ...

Chemoresistome mapping in individual breast cancer patients unravels diversity in dynamic transcriptional adaptation

open access: yesMolecular Oncology, EarlyView.
This study used longitudinal transcriptomics and gene‐pattern classification to uncover patient‐specific mechanisms of chemotherapy resistance in breast cancer. Findings reveal preexisting drug‐tolerant states in primary tumors and diverse gene rewiring patterns across patients, converging on a few dysregulated functional modules. Despite receiving the

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.

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.

Multimodal Autonomic Biomarkers Predict Phenoconversion in Pure Autonomic Failure

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Pure autonomic failure (PAF) presents with autonomic failure without other neurological features. A third develop central neurological features, fulfilling criteria for multiple system atrophy (MSA) and Lewy body diseases (LBD), including Parkinson's disease and Dementia with Lewy bodies.

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

Testing a dynamical origin of Standard Model fermion masses [PDF]

open access: yes, 2016
We discuss a test of the Standard Model fermion mass origin in models of dynamical electroweak symmetry breaking. The couplings of composite pseudoscalar resonances to top quarks allow to distinguish high-scale Extended-Technicolor-type fermion mass ...

Composite Higgsino [PDF]

open access: yesJournal of High Energy Physics, 2014
16 pages, 3 figures, v2: added references and comments, fixed typos and modified comments, in particular, the value of the annihilation cross section is modified and we explicitly describe the coeffeicient which depends on SUSY breaking and origin of the magnetic moment terms to avoid ...
