Summary: In the Type-II seesaw model, the introduction of an electroweak triplet scalar field Delta is essential for the generation of small neutrino masses. The non-zero vacuum expectation value of Delta affects the W mass, but recent data suggest that this effect can be neglected.

Summary: A new report from the CDF II experiment shows a significant deviation in the measured mass of the W boson compared to the standard model prediction. While other high energy experiments have consistent results, the possibility of explaining this anomaly using the Higgs triplet model is discussed.

Summary: The recent high-precision measurement of the W mass by the CDF collaboration is in tension with the Standard Model prediction. This work explores the connection between the MW anomaly and Higgs physics observables, and identifies new physics scenarios that can explain the MW anomaly.

Summary: We discuss the implications of the CDF collaboration's high-precision measurement of the W boson mass on models with a non-standard Higgs, showing that an enhancement of more than 5% in the non-standard Higgs coupling to gauge bosons is required. This can be naturally explained in dynamical models such as the dilaton Higgs, Technicolor, and glueball Higgs. The needed composite scale between 2 and 3 TeV can also account for the muon g-2 anomaly and potential violations of lepton flavour universality.

Summary: We reconsider the coupling of light vectors to anomalous fermionic currents, specifically examining the interactions between ultraviolet and infrared dynamics. By gauging the accidental symmetries of the Standard Model, we demonstrate the possibility of an anomaly-free ultraviolet completion using predominantly chiral heavy fermions, effectively suppressing anomalous Wess-Zumino terms in the infrared regime. This relaxation of constraints allows for extensive probing of these scenarios at the high luminosity phase of the LHC through measurements of the h -> Z gamma rate and direct searches for nondecoupling charged leptons.

Summary: The Type-II Seesaw model involves the introduction of a Delta field to generate small neutrino masses, affecting the W mass and rare neutrino trident scattering. Experimental measurements of the W mass have significant impact on the rho parameter, constraining the range of the vacuum expectation value of the Delta field.

Summary: The new report provides a measurement of the W boson mass which shows a deviation from the standard model prediction. The anomaly can potentially be explained by the Higgs triplet model under certain constraints.

Summary: The experiment presented the first results of the Fermilab National Accelerator Laboratory (FNAL) Muon g - 2 Experiment for the positive muon magnetic anomaly a(mu) (g(mu) - 2)/2, which determined the anomaly from precision measurements of two angular frequencies. The result showed a deviation of 3.3 standard deviations from the standard model prediction, in agreement with previous measurements, increasing the tension between experiment and theory.
