Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In certain new physics scenarios, a singly charged Higgs boson can couple to both fermions and WZ at tree level. We develop new strategies beyond current experimental searches using pp → jjH, H → tb at the Large Hadron Collider (LHC). With the effective HWZ and Htb couplings we perform a model-independent analysis at the collision energy s=13 TeV with the integrated luminosity of 3 ab. We derive the discovery prospects and exclusion limits for the charged Higgs boson in the mass range from 200 GeV to 1 TeV. With |F|, |A| ∼ 0.5–1.0 and 300 GeV ≲ mH± ≲ 400 GeV, we point out that a discovery significance of 5σ can be achieved. The constraints and projected sensitivities are also discussed in a realistic model, i.e., the modified Georgi-Machacek model without custodial symmetry. Our proposed search would provide direct evidence for a charged Higgs boson H that couples to WZ and tb, and has better sensitivity to the couplings of HWZ and Htb than current searches.
