Hi @singhra1994 , thanks for the fixes. Please see a few more suggestions.

[vkucera]

You have defined the V0LambdaType type. Use it and you don't need the casting to int.

Suggested change

	template <bool IsMcRec, int LambdaType, typename AssocType, typename McPart>
	template <bool IsMcRec, V0LambdaType LambdaType, typename AssocType, typename McPart>

[vkucera]

Suggested change

	if constexpr (LambdaType == static_cast<int>(V0LambdaType::Lambda)) { // Lambda
	if constexpr (LambdaType == V0LambdaType::Lambda) { // Lambda

[vkucera]

Don't use magic numbers. Use a named value of the same type.

Suggested change

	if constexpr (LambdaType == 0) { // Regular track
	if constexpr (LambdaType == V0LambdaType::NotLambda) { // Regular track

[vkucera]

Pass small types by value.

Suggested change

	void fillCorrelationTable(bool trkPidFill, AssocType const& assoc, float const& candPt, float const& candEta, float const& candPhi,
	void fillCorrelationTable(bool trkPidFill, AssocType const& assoc, float const candPt, float const candEta, float const candPhi,

[vkucera]

Suggested change

	std::array<float, 3> pVec2{assoc.px(), assoc.py(), assoc.pz()};
	std::array pVec2{assoc.px(), assoc.py(), assoc.pz()};

Suggested change

	auto trackV0Pos = assocParticle.template posTrack_as<TrackType>();
	auto trackV0Neg = assocParticle.template negTrack_as<TrackType>();
	auto const& trackV0Pos = assocParticle.template posTrack_as<TrackType>();
	auto const& trackV0Neg = assocParticle.template negTrack_as<TrackType>();
