A search for solar axions and axion-like particles produced in the p + d →3*He + A (5.5 MeV) reaction was performed using the complete dataset of the Borexino detector (3995 days of measurement live-time). The following interaction processes have been considered: axion decay into two photons (A → 2γ ), inverse Primakoff conversion on nuclei (A + Z → γ + Z), the Compton conversion of axions to photons (A + e → e + γ ) and the axio-electric effect (A + e + Z → e + Z). Model-independent limits on product of axion–photon (g&sub(Aγ)), axion–electron (g&sub(Ae)), and isovector axion–nucleon (g&sub(3AN)) couplings are obtained: |g&sub(Aγ) × g&sub(3AN)| ≤ 2.3 × 10&sup(−11)GeV&sup(−1) and |g&sub(Ae) × g&sub(3AN)| ≤ 1.9×10&sup(−13) at m&sub(A) < 1 MeV (90% c.l.). The Borexino results exclude new large regions of gAγ , and gAe coupling constants and axion masses mA, and leads to constraints on the products |g&sub(Aγ) × m&sub(A)| and |g&sub(Ae) × m&sub(A)| for the KSVZ- and the DFSZ-axion models.
