Probing TeV scale Top-Philic Resonances with Boosted Top-Tagging at the High Luminosity LHC
We investigate the discovery potential of singly produced top-philic
resonances at the high luminosity (HL) LHC in the four-top final state. Our
analysis spans over the fully-hadronic, semi-leptonic, and same-sign dilepton
channels where we present concrete search strategies adequate to a boosted
kinematic regime and high jet-multiplicity environments. We utilize the
Template Overlap Method (TOM) with newly developed template observables for
tagging boosted top quarks, a large-radius jet variable and customized
b-tagging tactics for background discrimination. Our results show that the
same-sign dilepton channel gives the best sensitivity among the considered
channels, with an improvement of significance up to 10%-20% when combined with
boosted-top tagging. Both the fully-hadronic and semi-leptonic channels yield
comparable discovery potential and contribute to further enhancements in the
sensitivity by combining all channels. Finally, we show the sensitivity of a
top-philic resonance at the LHC and HL-LHC by showing the exclusion
limit and discovery reach, including a combination of all three
channels.Comment: 19 pages, 14 figure
Boosted Event Topologies from TeV Scale Light Quark Composite Partners
We propose a new search strategy for quark partners which decay into a
boosted Higgs and a light quark. As an example, we consider phenomenologically
viable right handed up-type quark partners of mass TeV in composite
pseudo-Nambu-Goldstone-boson Higgs models within the context of flavorful
naturalness. Our results show that and signal significance of is achievable at TeV LHC with 35 of
integrated luminosity, sufficient to claim discovery of a new particle. A
combination of a multi-dimensional boosted Higgs tagging technique, kinematics
of pair produced heavy objects and -tagging serves to efficiently diminish
the large QCD backgrounds while maintaining adequate levels of signal
efficiency. We present the analysis in the context of effective field theory,
such that our results can be applied to any future search for pair produced
vector-like quarks with decay modes to Higgs and a light jet.Comment: 18 pages, 7 figures, 5 tables, v2: short discussion added in Sec. 2,

Corrosion Inhibitors for Reinforced Concrete: A Review
The objective of the topic is to review the recent trends in corrosion inhibitors for reinforced concrete and their application in the laboratory and field conditions. Inhibitors are chemical substances which when added to the concrete in small concentrations will inhibit or prolong the time to initiation of corrosion in concrete structures. This chapter focuses on the type of inhibitors used in concrete based upon their mode of action and the way of application. The section deals with anodic, cathodic, mixed inhibitors; performance of admixed inhibitor vs. migrating/surface applied inhibitor and their evaluation studies; and electrochemical injection of corrosion inhibitor (EICI) in concrete and electrochemical chloride extraction techniques has been reviewed
