## TL;DR

This paper investigates a quintessence field transitioning from matter-like to dark energy behavior to address the Hubble constant tension, but finds that such models are not effective solutions.

## Contribution

It evaluates a dynamic quintessence model against cosmological data and demonstrates its inability to resolve the Hubble tension, excluding this class of models.

## Key findings

- The quintessence transition model does not alleviate the Hubble tension.
- Such models can be excluded as solutions to the Hubble constant discrepancy.

## Abstract

We consider a quintessence field which transitions from a matter-like to a cosmological constant behavior between recombination and the present time. We aim at easing the tension in the measurement of the present Hubble rate, and we assess the $\Lambda$CDM model properly enlarged to include our quintessence field against cosmological observations. The model does not address the scope we proposed. This result allows us to exclude a class of quintessential models as a solution to the tension in the Hubble constant measurements.
