In-medium properties of pseudoscalar $$D_s$$ D s and $$B_s$$ B s mesons

Abstract

We calculate the shift in the masses and decay constants of D s (1968) and B s (5370) mesons in hot and dense asymmetric strange hadronic matter using QCD sum rules and chiral SU(3) model. In-medium strange quark condensates ss ρ B , and gluon condensates

Temporary Surface Passivation for Characterisation of Bulk Defects in Silicon: A Review

“…[53] Chhabra et al demonstrated that a moderate level of surface passivation is retained when the silicon samples are taken out of the quinhydrone-methanol solution. [57,58] For 1 Ω cm n-type silicon they achieve S of 12.6 cm s À1 (in solution) and 60.7 cm s À1 (out of solution), however for 100 Ω cm n-type silicon they achieve S of 7 cm s À1 (in solution) and 8.5 cm s À1 (out of solution).…”

“…[53,55,56,59] In general, three benzyl species have been examined, hydroquinone (HQ), p-benzoquinone (BQ), and quinhydrone (QHY), where the latter is the combination of HQ and BQ. Of the three benzyl species, quinhydrone dissolved in methanol provides superior surface passivation when its concentration is 0.05 to 0.1 M. [58,59,60]…”

“…In the surveyed literature for benzyl-alcohol passivation, the favored wet chemical pre-treatment is the piranha etch followed by a dilute HF dip [46,53,[57][58][59] . In contrast to halogen-alcohol passivation, an S below 1 cm s À1 has not been reported for benzyl-alcohol passivation, which could be a consequence of the relatively unexplored wet chemical pre-treatment processes.…”

A 14‐Protein Signature for Rapid Identification of Poor Prognosis Stage III Metastatic Melanoma

“…[40][41][42][43] Gp96 binds peptides for presentation to the major histocompatibility complex class I protein (MHC-I) thereby activating a CD8 + T-cell immunogenic response. [75][76][77][78][79] Due to its ability to elicit a tumor specific response, new immunotherapies and vaccines based on Gp96 are under trial. [80,81] Rivoltini et al have shown that T-cells activated with melanoma cell line-derived Gp96-peptide can trigger cytotoxic activity in stage IV melanoma patients.…”

Charmonia and bottomonia in asymmetric magnetized hot nuclear matter

“…The chiral SU(3) model is used vastly to investigate the in-medium properties of light mesons in nuclear and hyperonic matter [49,62,63]. To study the in-medium properties of heavy D and B mesons, this model is also generalized to SU(4) and SU(5) respectively [47,48,64,65]. In this model, the scalar and tensorial gluon condensates are extracted in terms of in-medium non-strange meson field σ, the strange scalar meson field ζ, the scalar isovector meson field δ, the vector meson field ω, the vector-isovector meson field ρ, and the dilaton field χ [46].…”
