Color-Octet Contributions to J/psi Photoproduction via Fragmentation at HERA [PDF]

open access: yes, 1997
We study J/psi photoproduction via fragmentation at next-to-leading order in the QCD-improved parton model, using the nonrelativistic factorization formalism proposed by Bodwin, Braaten, and Lepage.

Quantum coherence, top transverse polarisation and the Tevatron asymmetry AFBℓ

open access: yesPhysics Letters B, 2014
We revisit the relation between the asymmetries AFB and AFBℓ in tt¯ production at the Tevatron, using as new physics benchmark a colour octet. We find that AFBℓ receives large contributions from the interference between λ=±1/2 top helicity states, which ...

U(3) chiral perturbation theory with infrared regularization [PDF]

open access: yes, 2001
We include the eta-prime in chiral perturbation theory without employing 1/N_c counting rules. The method is illustrated by calculating the masses and decay constants of the Goldstone boson octet (pions, kaons, eta) and the singlet eta-prime up to one ...

From Single to Multi‐Glass/Ceramic Microarchitectures via Two‐Photon Lithography

open access: yesAdvanced Optical Materials, EarlyView.
Two‐photon lithography enables precise oxide microarchitectures. A transition is made from single to multi‐glass/ceramic materials by integrating spatially varied compositions via fluidic photoresin exchange. Low‐temperature annealing and optical characterization (i.e., cathodoluminescence, fluorescence microscopy) reveal how post‐treatment affects the

Neutron Electric Dipole Moment from colored scalars⋆

open access: yesEPJ Web of Conferences, 2014
We present new contributions to the neutron electric dipole moment induced by a color octet, weak doublet scalar, accommodated within a modified Minimal Flavor Violating framework.

Gauge Invariance, Color-Octet Vector Resonances and Double Technieta Production at the Tevatron

open access: yes, 2001
We show that the usual vector meson dominance method does not apply directly to the mixing of a color-octet vector boson (color-octet technirho) with the gluon because of gauge invariance. We propose a gauge invariant method where one works in a physical

HERV‐K TM Subunit Elicits CD8+ T Cell Anergy and Tumor Immune Evasion via Targeting CD3 Coreceptor ε in AML and PDAC

open access: yesAdvanced Science, EarlyView.
Novel viral immune checkpoint K‐TM subunit is aberrantly expressed in CD8+ T cells and enriched in sera of cancer patients, inducing CD8+ T cell anergy and eliciting potent tumor immune escape in mouse model. Mechanistically, K‐TM directly targets and induces the phosphorylation of CD3ε receptor.

The contribution of color-octet current color-octet current toD decays [PDF]

open access: yesZeitschrift für Physik C Particles and Fields, 1989
Bauer and Stech pointed out that inD decaysa1 anda2 are approximately equal toc1 andc2 obtained from the renormalization group equation. This means that the non-leading 1/N c term in the formulation vanishes. Many authors conjecture that there is a cancellation between the 1/N c term and an extra term emerging from the analysis of non-factorizable ...

Novel Antimicrobial Protein Fibroblast Growth Factor 8 Accelerates Skin Wound Healing via Directly Inhibiting Bacteria and Activating Glycolysis

open access: yesAdvanced Science, EarlyView.
Wound infections induce gcFGF8a expression, which subsequently executes direct antimicrobial activity to suppress local infection while simultaneously activating the FGFR4‐mediated ERK/AKT‐mTOR signaling cascade, thereby upregulating HIF1α and enhancing glycolysis. These coordinated actions synergistically promote tissue repair by eliminating pathogens
