Trinification from E 6 symmetry breaking

Journal of High Energy Physics, 2023
In the context of E6 Grand Unified Theories (GUTs), an intriguing possibility for symmetry breaking to the Standard Model (SM) group involves an intermediate stage characterized by either SU(3) × SU(3) × SU(3) (trinification) or SU(6) × SU(2).

Tree-level Unitarity in SU 2 L × U 1 Y × U 1 Y ′ $$ \textrm{SU}{(2)}_L\times \textrm{U}{(1)}_Y\times \textrm{U}{(1)}_{Y^{\prime }} $$ Models

Journal of High Energy Physics, 2023
In models with a U(1) gauge extension beyond the Standard Model, one can derive sum rules for the couplings of the theory that are a consequence of tree-level unitarity.

Interacting quintessence from new formalism of gravitoelectromagnetism formulated on a geometrical scalar–tensor gauge theory of gravity [PDF]

Physics of the Dark Universe, 2018
We derive an interacting quintessence model on the framework of a recently introduced new class of geometrical scalar-tensor theories of gravity formulated on a Weyl-Integrable geometry, where the gravitational sector is described by both a scalar and a tensor metric field.

Interactions of particles with “continuous spin” fields

Journal of High Energy Physics, 2023
Powerful general arguments allow only a few families of long-range interactions, exemplified by gauge field theories of electromagnetism and gravity. However, all of these arguments presuppose that massless fields have zero spin scale (Casimir invariant)

Impact of dimension-8 SMEFT operators on diboson productions

Journal of High Energy Physics, 2023
We for the first time identify all the dimension-8 (dim-8) SMEFT operators that can have an interference with the SM with E 4/Λ4 enhancement in the high energy limit for the processes q q ¯ → WW / WZ $$ q\overline{q}\to WW/ WZ $$ .

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

Searching for the neutral triple gauge couplings in the process μ + μ − → γν ν ¯ $$ {\mu}^{+}{\mu}^{-}\to \gamma \nu \overline{\nu} $$ at muon colliders

Journal of High Energy Physics
We investigate the sensitivity of future high-energy muon colliders to neutral triple gauge couplings (nTGCs) through the process μ + μ − → γν ν ¯ $$ {\mu}^{+}{\mu}^{-}\to \gamma \nu \overline{\nu} $$ within the Standard Model Effective Field Theory ...

Pathogenic Germline PALB2 and RAD50 Variants in Patients With Relapsed Ewing Sarcoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Approximately 10% of patients with Ewing sarcoma (EwS) have pathogenic germline variants. Here, we report two cases: first, a novel germline pathogenic variant in partner and localizer of BRCA2 (PALB2) in a patient with a late EwS relapse. Its impact on homologous recombination is demonstrated, and breast cancer risk is discussed.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

A quantum machine learning classifier to search for new physics

Journal of High Energy Physics
Due to the success of the Standard Model (SM), it is reasonable to anticipate that the signal of new physics (NP) beyond the SM is small. Consequently, future searches for NP and precision tests of the SM will require high luminosity collider experiments.
