The scalar and vector leptoquark pair production cross sections in hadronic collisions are calculated. In a model independent analysis we consider the most general C and P conserving couplings of gluons to both scalar and vector leptoquarks described by an effective low–energy Lagangian which obeys SU(3)c invariance. Analytrical expressions are derived for the differential and integral scatteri...

We discuss contact-interaction searches in the processes ee → μμ, bb̄ and cc̄ at an ee Linear Collider with c.m. energy √ s = 0.5 TeV and with longitudinally polarized beams. The measurement of polarized cross sections allows to study the individual helicity cross sections, and consequently to derive separate, model-independent, constraints on the four-fermion contact interaction couplings. We ev...

We present a study of single-W production (ee → eν̄eW ) as a new probe of the anomalous couplings at the LEP energy region. We introduce simple cuts to separate the single-W process from Wpair production and have performed cross-section calculations using 4-fermion generator “grc4f”. The cross-section of the single-W process is found to be large enough to detect at LEP experiments in the near fu...

Yukawa couplings between Higgs bosons and quarks in supersymmetric theories can be measured in the processes ee → QQ̄ + Higgs. We have determined the cross sections of these processes in the minimal supersymmetric model including the complete set of next-to-leading order QCD corrections for all channels. Supported by the EU FF Programme under contract FMRX-CT98-0194 (DG 12 MIHT). Heisenberg-Fell...

A wide array of cross-coupling methods for the formation of C-C bonds from unactivated alkyl electrophiles have been described in recent years. In contrast, progress in the development of methods for the construction of C-heteroatom bonds has lagged; for example, there have been no reports of metal-catalyzed cross-couplings of unactivated secondary or tertiary alkyl halides with silicon nucleop...

Boson pair production is one of the few processes that have significant effects from triple boson vertices at tree level. These couplings are predicted in the standard model and are directly related to its gauge group structure. One of the goals of diboson measurements is to limit deviations from the standard model values of these triple gauge couplings (TGCs). Such deviations could be observed...

Carbon dots have been immobilized on titanium dioxide to generate photocatalysts for metallaphotocatalytic carbon–heteroatom cross-couplings.

A microscopic calculation of the optical potential for nucleon-nucleus scattering has been performed by explicitly coupling the elastic channel to all the particle-hole (p-h) excitation states in the target and to all relevant pickup channels. These p-h states may be regarded as doorway states through which the flux flows to more complicated configurations, and to longlived compound nucleus res...

Abstract Proteolysis‐targeting chimeras (PROTACs) have recently emerged as powerful molecules for targeted protein degradation. As such, synthetic methods their modular synthesis are of prime importance in medicinal chemistry. We report the development both batch and flow photoredox methodologies C sp 3 −C 2 cross‐electrophile couplings alkyl bromides with E3 ligase‐binding aryl (thalidomide le...
