| Sumario: | In this paper, we briefly review the LHC discovery potential of a light pseudoscalar Higgs boson of the NMSSM, <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>a</mi><mn>1</mn></msub></semantics></math></inline-formula>, produced in the gluon fusion <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>g</mi><mi>g</mi><mo>→</mo><msub><mi>a</mi><mn>1</mn></msub></mrow></semantics></math></inline-formula>, bottom-quark fusion <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>b</mi><mover accent="true"><mi>b</mi><mo>¯</mo></mover><mo>→</mo><msub><mi>a</mi><mn>1</mn></msub></mrow></semantics></math></inline-formula> and bottom-gluon fusion <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>b</mi><mi>g</mi><mo>→</mo><mi>b</mi><msub><mi>a</mi><mn>1</mn></msub></mrow></semantics></math></inline-formula>. We also review the LHC discovery potential of the next-to-lightest CP-even Higgs boson <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>h</mi><mn>2</mn></msub></semantics></math></inline-formula> being the non-SM-like Higgs, decaying either into two light CP-odd Higgs bosons <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>a</mi><mn>1</mn></msub></semantics></math></inline-formula> or into a light <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>a</mi><mn>1</mn></msub></semantics></math></inline-formula> and the <i>Z</i> gauge boson through the gluon fusion <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>g</mi><mi>g</mi><mo>→</mo><msub><mi>h</mi><mn>2</mn></msub></mrow></semantics></math></inline-formula> in the 4<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mi>τ</mi></semantics></math></inline-formula> final state. We find that the light <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>a</mi><mn>1</mn></msub></semantics></math></inline-formula> can be detected at the LHC in a variety of production processes including the gluon fusion, bottom-quark fusion and bottom-gluon fusion. The latter two processes require high luminosity of the LHC and large values of tan<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mi>β</mi></semantics></math></inline-formula>. We also find that the LHC has the potential to discover the non-SM-like Higgs state, <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>h</mi><mn>2</mn></msub></semantics></math></inline-formula>, decaying into a pair of light CP-odd Higgses <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>a</mi><mn>1</mn></msub></semantics></math></inline-formula>’s, allowing the distinguishing of the NMSSM Higgs sector from the MSSM one as such a light <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>a</mi><mn>1</mn></msub></semantics></math></inline-formula>, is impossible in the latter scenario. |
